Artist Mike Doscher has made several great-looking pieces of dieselpunk art.
Here is a jet-glider in a German Luftstreitkräfte livery from 1918. It would easily find its place in any of my three dieselpunk worlds: Alba (i.e. The Ice War), Lemuria and Patchwork World. Also, it would not have been inappropriate in the recent movie about Wonder Woman in World War One.
