Mooney carved these when he was travelling on the road with his carvings in the 30's, 40's and 50's. He packed wood blanks and would spend an evening carving a message and sending them to relatives and friends. There is only this one known to have been sent through the mails:
The Ernest Warther Museum and Gardens in Dover, Ohio web site is https://thewarthermuseum.com/ernest-warther-story
They have at least a dozen, that were sent to mostly family, at the museum. They have no idea how many he did or where they might be. They suspect the bulk of them were sent to people locally as this was mainly where his friends and family were. But through families moving about and passing things to the next generation, they could be anywhere.
Can you supply additional examples of these cards or any information on sightings of these treasures?
