Vintage Postcard Jackalope Roundup Time Cowboy Cow Ranch Unposted 70s

Vintage post card from the 1970s featuring the mystical Jackalope.  This post card has never been posted but it has yellowed from age and shows wear in the corners.  Measures approximately 6 inches by 4 inches.   "This rare species of Jackalope used in cattle round ups are very dependable and easily trained. A breed of Antelope and Jackrabbit. Their cries often sound human and tuneful, probably from hearing cowboy songs at roundup time"
