I'm mostly going for collections of single Pokemon, but ones of all your plush, zukan, or just your whole collection are fine too, of course ^_^ It'd also be neat if you could include dates, so we can see how quickly (or slowly ;) ) your collection is progressing.
I'll start us off with my Jolteon:
From about a year ago (9/30/07) when I first joined the comm. The cel still is my rarest item, though!
And now, with many figures from YJ, and the comm! I do have the zukan as well, but it's not shown here, as it's on my zukan shelf~
And my largest collection:
Hahahahahahaha. This is from also about a year ago, 9/30/07. I had picked up a few things from Pokemon Center.com (it was still open then) and had started getting things off eBay as well.
Now? I don't have things well enough organized to put them all in one picture, but I tried and here is the result:
This doesn't quite fit everyone, so here is a close up of just the figures (from June, so a little outdated but not much):
I also have an item-by-item index at my site, Dialga FTW. ^_^ (If you've seen it when I last posted, I added several new items, so the count is a little bit higher!)
Let's see your collections!
