Just 51 cards in the set with Toronto (#1-#18) Detroit (#19-#34) and Montreal (#35-#51) pictured. The backs feature a big cartoon, and you are encouraged to rub a penny under the cartoon to reveal the punch line. I know my eyesight isn't all that great, but I can't read ANY of these scratched off punch lines.
I have 33 of these so far about 64% of the set.
