I really believe the photo George saw in the magazine was just wishful thinking on his part.
Perhaps the senders of the letter were foreign and writing in English? Maybe Italian like George.
Rather that meaning

A90135 - either meaning the location in Italy or license plate of Kentucky car??
So playing on this, what caught my eye first, when hearing the story was the A90135. I immediately noticed it as a possible phone number. I'm from a very rural area in the south that didnt get 10 digit phone numbers til the early 70s. Most of the country had switched from the original "mapped" numbers where the letters represented a district or county for the switch board operators by the early 60s, but again, not everywhere, and certainly not in other countries. There are just so many clues to this case that noone bothered with, it drives me crazy. Of course there is no way to call or lookup that number now.
It is MASSIVELY frustrating to me that so much was ignored or disregarded/never bothered being looked into. There are so many holes it makes my brain want to explode
