Paul Cunningham was (or is) a Nebraska artist who specialized in box dioramas depicting scenes from the life of Christ, which were for a time on display at a Florida museum called Prince of Peace. More examples of his work can be found on the Web here and here, and postcards of his dioramas are often available on eBay. Thanks to the site’s reader who brought this to our attention (and whose name unfortunately has been lost in the in-cue!).
