Irvin Penn's book Small Trades is one of my favorite photo books I own. It's a perfect slice-of-life, documentation of a bygone era, simply photographed in a way that illustrates unique facets of tradesmen I'd otherwise be completely unaware of.
There's a ton of little things slipping by even still and I try my best to notice them but I'm sure I miss more than I see (which is why I'm glad people like Caleb Chancey exist to create projects like his We Make Birmingham he shot for Birmingham Magazine, which is a series of photo essays on various craftspersons around town).
All that to say, I saw a dude hand painting a neon sign while scooting downtown the other day and 100% had to shoot him working. I have his card somewhere...I'll update this with his name at some point.
