I am looking for a company that sells folded Post cards that I may attach my 4x6, 5x7, Landscape images, as a business venture. Many & All suggestions will be appreciated. Thanks on 5/11/2020
I don't think a postcard is folded. If it was, the post office couldn't handle it - unless it was somehow closed with a sticker. Single layer, double-sided postcards can be handled by many printers. I would google "postcard printing" for your area.
