Yes, those were made for customers to make their own do-it-yourself postcard. They consist of two parts - the front part with a round cutout area with a white border that would frame a photo that you put in from the behind along with a back flap that would be glued down to secure the photo. Here is an example that the Springfield Ponies of the Connecticut State League did for their team. Others exist where customers would insert a generic image of themselves, friends, family members, etc.
