The DAV Keychain Tags

From the early 1940s to the mid-1970s, the Disabled American Veterans (DAV)  mailed these tags to owners of registered vehicles in various states. The license plate number was on one side and the DAV’s address and instructions were on the other to serve as a means for returning lost keys. Also included was a request for a donation to the DAV. When a set of lost keys with this tag was found, following the directive to drop them in a mailbox would get them to the DAV where the staff would match the plate number on the tag with the address of the registered plate owner, and then the keys would be returned.
