Just found your blog..I have some strips and googled what they were for! I don't remember playing with them, howeer. I have Scooby Doo, Vally of the Dinosaurs, Hong Kong Phooey, Speed Buggy, Korg 70,000 bc, Wheelie and the Chopper bunch....15 in all. Wondered what to do with them and what they may be worth, dated 1974. :)
My best advice for you would be to either keep them, or decide to put them on eBay. I'm pretty certain I have all the 1974 stuff myself. Sounds like your set was one slide short (there were 16 slides per set), but there may well be someone out there who has an incomplete set. I'd suggest offering them at a starting price of $5 to $9, depending on the overall condition of the slides.
