Help making postcard holders for TWF

It would be awesome if we could further round out our table display at Texas Woodworking Festival this weekend with a wooden holder for our postcards. Doesn’t have to be anything super fancy, just something that can nicely display a stack of 4x6 postcards (there are usually some laying around the space in the lounge area, pic below for reference).

This is way fancier than necessary, but something similar where we could maybe do clear acrylic for the front part holding postcards from sliding forward is nice, that way the full face of the postcard can be seen. Only needs to be single tier, but two of them would be good.
