1940 Hillbilly Takes Cow to City Comic Postcard

1940s Hillbilly humor vintage comic postcard. A farmer walking his daffy cow is stopped by Police Officer Friendly. A man milks the cow from an opened manhole in the street. The card is mocking the farmer for traveling from the country and not having any city smarts. "Having a grand time here - and this is no bull". 'No Bull' is a pun because the cow pictured is a female (heifer) and not a male (bull).
