Is there a photo “frame” that conceals several photos behind the one on display, making it easier to change them regularly?

I’ve been given several prints that are very special to me. I would like a kind of frame “box” that shows the top photo in the “deck”. I’m also conscious that having the photos touching each other isn’t ideal.Any existing solutions or recommendations for this? via /r/photography https://ift.tt/0P1LX6O
