Wow! Gasped when I found this one.
Small Expo 67 mug. Double finger handle. Blue band at top and bottom, which reads "Expo 67, Canada." Very cool trees-in-a-circle (haha) logo in centre. Bottom stamped copyright, 1963, Canadian Corporation for the 1967 World Exhibition. So, so cool. A small small chip on base- sort of the beginning of a chip. As is!
