2 deck set of DOHRN TRANSFER playing cards, 1960's

Two decks of "REDISLIP" playing cards featuring a portrait of a DOHRN TRANSFER tractor-trailer, in a red plastic box with the DOHRN logo in gold on its cover. Guessing their age at mid 1960's, based on the look of the truck and my own memories of playing with these as a kid. :-)

A quick look around the interwebs suggests that DOHRN TRANSFER is still in business today.
