or rather, why didn't i ever to think to look before?
because etsy? has a vintage section in addition to a handmade section.
so i did a search for fisher price toys. and found this:
HOLY HELL, BATMAN, I'M SO HAPPY.
((i may or may not have a slight obsession with vintage toys. particularly of the fisher price persuasion. don't even get me started on the little people toys. O.M.G))
eta: i'm pretty sure cash is going to be completely uninterested in planes, since EVERY SINGLE THING i buy him has an airplane on it.
