Over the years, I have managed to amass a nice collection of these. They are just so pretty in all of their lovely colors! All but one of the tumblers are marked Bascal, the coasters have no marking, the pitcher is marked "Flamingo by Nasco Italy":
The little "shot glasses" (how cute are they?) are marked "Made in Germany", and I just found the two trays recently at a thrift shop - they appear to be new.
They sure do look nice all together like this, don't they? Come on over for a nice icy cold cup full of SOMETHING - I've got plenty of tumblers!
