Art, I can't explain that I'm afraid but even more bizarre is that in a documentary which I cannot recall the title of it shows Arvella running his films for the benefit of Jimmy Brewer. I never met Arvella so don't know if perhaps he had a litle vision but in my brief meeting with Jimmy I was convinced that he had none at all.
Perhaps he thought that there might be some money to be made from filming the famous street market and selling the results to the blues enthusiasts. I remember personally buying a well thumbed and grubby copy of a book about Maxwell from a Maxwell Street musician (his picture was in it) and paying about double the price for which it was available in a book store, I was unaware that it was still available. I'm sure Arvella was very street wise and realised how many gullible collectors there were out there at the time, so maybe that was it.
