I recently scored this Wire Photo Holder at my local thrift shop. Although it is not a vintage item, I like the looks, sturdiness and cost of this piece - only $2.99.
Besides photos, you can use these holders for postcards, recipes, greeting cards or small works of art. I'm going to use mine for my collaged postcards.
When I need a light background for taking pictures, I lay a large piece of white Foam Core Board on the table. For the background, I prop another piece of the board against a heavy bottle so that the vertical board meets flush with the horizontal board.
