Slurpee Cups: As I've shown in the picture-laden posts of "Doug's Stuff", I have a fair collection of Slurpee Cups. All of the ones I have were purchased with that frozen concoction inside -- sometimes I fantasize about going on eBay and beginning to collect a really nice set of all of them, Marvel and DC. But I'm so stuck in the trade paperback/hardcover buying mode that I doubt I'll get to it. It's really amazing that the cups have lasted, as the plastic of which they're made is not of the highest quality; in fact, they can be quite brittle.
Third Eye posters: Again, as I'm sure I've mentioned in the past, I have two of these -- the Fantastic Four and Medusa. I also have a Dr. Strange greeting card that I did purchase via eBay at some point. If you're not familiar, these are black light posters that are really quite garish. I won both of them at a carnival when I was around 10 years old, throwing darts at balloons.
Topps Superhero Stickers trading cards: How about these? Did you have any of these stickers? They were pretty silly, but I was just so comics-crazed at that point in my life (1975 -- I would have been 9 years old) that I would beg for anything I saw that had Marvel's characters on it. I think I still have three or four sheets of construction paper with these stickers affixed to them!
Doug: So there are a few ideas to get your memory working. What of the above did you dabble in, and certainly what else not mentioned did you try to get your grubby little mitts on? Thanks in advance!
UPDATE (3/16/13) Here are the three sheets of construction paper with my Topps Marvel Superhero stickers affixed; I'd mentioned this in yesterday's comments. Doug
