I collected Lost Word: Jurassic Park movie trading cards. Never did get the full set. And of course, like most, I had CCG/TCG game cards; Pokemon, Gundam Wing, Dragon Ball Z, Star Wars, and Star Trek. Got rid of most all of them though over the years though.
I'm actually gifting some art for Christmas this year though. Picked up a original black & white Han Solo publicity photo, very early 1980's vintage and framed it for my sister as she's had a massive crush on Harrison Ford ever since she was a teenager. Also picked her up a vintage poster-sized wood framed unicorn airbrush painting, because she's also been really into unicorns since she was a teenager, and I figure she'll either love it or regard it as the best gag gift ever, only time will tell.
