Unfortunately, Ross Walker and Toshikazu Doi, in their Koitsu catalog raisonne, are totally dismissive of this print. They claim that even though it is dated in 1939, that it has to be a post war production. They seem to doubt that it was designed by Koitsu, implying that it was a publisher-driven modification of a smaller format design from 1936. They outright call the rendering of the woman as a "poor drawing".
I strongly disagree with my esteemed colleagues. The visible woodblock grains in the lower part of the background identify this is as a very early edition. I see no reason to doubt the margin dating of April, 1939. There is a Doi watermark in the upper left margin. I'm calling this a first (or very early) edition pre-war print. That's my story and I'm sticking to it!
This print is on paper a bit too large to catch it all in my large-format scanner. See the "Extra picture" link below to see the complete upper margin.
