Hi Kathy. I think your old post cards would look great in a shadow box. Besides the post cards, put some little trinkets in too. You could also get a large map and clip the post cards to the place where they are from. Good luck Kathy. Stay well.

Hello there,

First let me suggest you try to sell them individually or as sets or groups, as there are various collectors out there.

Otherwise, frame them up and use on bathroom or waiting areas to give guests something to entertain them.
