I am mainly a collector of any thing that catches my eye. Because I like Yard Sales and Flea Markets, I have lots of junk. Therefore, I sell stuff. I still don't consider myself a dealer. If I am a dealer, I'm a very bad one.
I mostly like Sci-Fi (Star Trek, Star Wars, Dr. Who, Godzilla). I like toys (50/60's Space, Legos, Die Cast, Action Figures). Also, I'm a collector Non-Sports Cards. I used to collect comics, and buy some select stuff (Mouse Guard, Usagi Yojimbo, Sergio Aargones'), but I don't collect any more.
I do collect art items that related to the above. Maybe I'll post some my stuff.
