Here's the sort of thing I'm doing. From my World Birth Year set: And from my Japanese Occupation of China category: Nothing fancy about them. I just want good images and informative labeling. P.S. This is a long, slow process. But with the "sheltering in place" I've got the time.
I've got Photoshop Elements and I use it to put the displays together. For the text I believe I use Times New Roman Bold. It's a nice proportional font with serifs.
Looks like Amazon has a down-loadable 2020 version on special at the moment for about $60. Be advised, there is a learning curve involved with Photoshop Elements with varying levels of difficulty depending on the function you're attempting.
