I’ll post it here, too, but I’m wondering if there is a website or Facebook group or Reddit group or something more specalized in something like this more likely to have info.
I found these in a five and dime around 20 years ago. Sold individually from a bin, less than $1.00 each. Around 2 inches in size, they have no marks except for China and a number. Goes up to 10, though I have only 8 of the designs. I always thought the designs were really clever, and wondered if they were a rip-off of something or original to Generic Chinese Plastics Plant Number 102F, and if they are something rare-ish from only one source or copied and sold by many companies, like the generic dinosaur toys. (I’d also love to see the apparently at least two designs I didn’t find.)
