Not really much info on the sketch right now. My sister-in-law gave it to me for Christmas 2 or 3 years ago. I don't know who did it, nor remember where she got it, nor how much it was - but I bet it was less than $20. I'd imagine it's a reproduction. I'll have to ask here about it the next time I see her. For living across the street we don't actually talk very often.
The cards next to the drawing are also kind of cool, and actually the item of second greatest age that I own. I'm not into vintage figures and the like, but I kind of like the cards. It's a set of 30 Topps cards, 5x7 in size, that my father-in-law bought me last year when I graduated with a BS. He found a complete set on ebay, in extremely good condition - they're Empire Strikes Back collectors cards, so about 25 years old. I have no idea how much he paid, and fear he may have actually paid a lot. My wife framed those seen on the wall, and I've been getting frames to display some of the other cards.
Since it appears there's now a thread for my collection I'll try and update it occasionally as I get new pics.
For those who like to collect figures MOC here's a couple pictures of my daughter Katie, who also like Star Wars toys.
