Ha!

I should have known — this publication still exists. It’s published quarterly, which was probably true in the 1920s also. Was and is published by the same company who produced the ORER and the Official Guide, which of course also still exist.

I also did a quick search on eBay, and there are a lot of recent ones from the 1960s to 1990s, (which are still labeled as ‘vintage’ by some of the sellers), but not any earlier than 1936 or 1937. If he had a long career, he might actually be in one of those.
