Lots of tiny cups / mugs...

i picked these up at the yardsale too. the previous owner said that these were used by his children to play a game. but i think that they have different origins. only one is marked 'Japan', and some of them appear to be made in Mexico, while the two dark brown ones appear to be very well-made. some are hand built, while others were produced in molds. the tallest one is under 2" tall.
