We collect postcards and I happened to find this in a little shop in Florida.
As you are related to the individuals noted, I'd be delighted to send you the card, actually. I know it will be much more valuable to you than whatever I can get on eBay.
So that you don't think I'm scamming to get your address, would you send me your email so I can attach the scans to that. (I don't know how to attach sscans to this message.) Then you can let me know if you'd like the actual item.
Thanks so much for responding. I just love finding the real people in the pictures. Someone had lots of foresight to put the names of the subjects on the back.
