From Chuck to Diane

This is one of those styles of lettering that I love - every time I see it, and keep hoping I will have time to do it myself and then I forget. I wonder if anyone has ever converted it into a font

I wonder if there is any way to learn where it came from?

There is a group called Letterheads that has been around for a long time. Originally, they were sign painter aficionados. I suppose they still are. I will resist the temptation to go down that rabbit hole - but anyone who has tons of time to kill and loves lettering - go for it.
