Here are two completely random, ordinary decks with no theme at all. One is "Aviator" (made by The U.S. Playing Card Co.) and the other is made by Hoyle. (USPC Co. is probably the company that makes most of the themed card decks I own, but I don't really don't take much interest in who makes what, usually.)
$100 bill. Because it's all about the Benjamins.
Amish Country. Here's the back, as well as the Joker (which I think is pretty cool), and the Ace of spades (which has a windmill, the only thing about any of the regular cards that is at all unique). I'm not positive when or where I got these, but it may have been sometime in 2003-05, when my sister and I were living in Ohio.
Big Dogs. This is something my sister gave me at some point, because she was big into the whole Big Dogs brand, for awhile. It's not something that ever interested me in the slightest, but a gift is a gift.
Budweiser lizard. You may remember the lizards from a series of Budweiser commercials. One of them, Louie, wants to be an actor. So there's one card in this deck with his bio, but otherwise the cards are all pretty normal. I will say this: the box the cards came in says "Learn about lizards and internet fun facts inside this deck. Do frogs really taste like chicken?" There are no such facts in the deck, however. Rip-off! (Note, the URL at the bottom of the bio is gone now, but it has been archived).
Canadian flag. Yup, as you can see, the back of these cards is just a Canadian flag. I don't recall for sure when I got these, but I'm assuming it was most likely something my sister gave me when she was attending a Canadian university. Maybe.
Dogs playing poker. Two decks of cards that came in a tin. Both paintings are by Cassius Marcellus Coolidge. The first one here, "His Station and Four Aces," is the picture used on the lid of the tin. The other one is "A Friend in Need."
Gypsy Witch fortune telling cards. (I didn't name the cards, but I offer my apologies to any Romani or Wiccans who may be offended.) Each card has on the front a different drawing and a text explanation of what it means. It's basically like Tarot cards, I guess, and there's a little booklet that explains how to do readings. But if you prefer, you can just ignore all that and use them like regular playing cards. (Maybe someday I'll feel like scanning all of the cards and moving this to a separate page, but for now... meh. I don't care enough. Which surprises me, because I actually think the deck is pretty cool.)
Holly. Just plain and simple holly. If I were going to be playing cards at Christmas, this would probably be my go-to deck (more so than, say, Coca-Cola Santa cards). Because... these are expendable.
Invisible cards, by Kikkerland. The cards are all transparent, except for the circles on the backs that obscure the ranks and suits on the fronts.
Klutz. Just normal playing cards... which seems a slightly odd thing, coming from Klutz. I don't remember, but I'd be surprised if this deck didn't originally accompany something else, like a magic book maybe. If it did come with something, I'm fairly sure I no longer have it. Just the deck of cards. Oh well.
Presque Isle. These are cards I think I probably must have bought when I was attending the University of Maine at Presque Isle.
Star Wars 3-D playing cards with collectible tin. The tin itself is nothing special. I wouldn't really call the cards "3-D," but they have lenticular images on the fronts, which in case you don't know, are those pictures that change when you tilt them. So each card actually has two pictures, which is neat in theory, but impossible to properly scan. (Incidentally, this isn't a scan of a card back or front, at least not a playing card. It's an insert from the package that's just there to give you an idea of what to expect the cards to be like, without actually opening the box or the tin.) I think I gave this deck to my cousin Andrew.
Steampunk. I picked up this deck which cost way too much for a simple deck of cards, especially considering there's not much in the way of different designs. I've taken a picture of the box from the Theory 11 website, though I should say my own box is a shinier gold color, whereas the pic on the site looks more like a dull brown, as you can see. I scanned the only three other things that are special about the deck: the ace of spades (the only ace that is special), the joker, and the card back. There's nothing wrong with the cards, but I was hoping for more different designs on each rank, at least. But they're all just normal cards. Oh well.
