We've bought almost all of them through Etsy, and they are indeed "random bespoke" products. Some sellers are military spouses so they design prints of the places where we've lived (i.e. around Army bases, which wouldn't interest most other people). Last week we were looking at this one, and the seller appears to specialize in artistic maps: https://www.etsy.com/listing/346969594/fort-rucker-map-print...
