Found on a bridge in Maine, built by the WPA as part of Roosevelt's 'New deal'.
had a look around the web, but there doesn't seem to have been a 'standard' typeface
this one is lovely, does anyone know its origins?
all the best

Back in Ye Olden Tymes, when people did hand lettering, there was an abundance of instructional books for aspiring artists, and there was a lot of "borrowing" among the various authors. The earliest "probable influence" I can find in my collection is an undated (but probably early 30s) version of "abc of Lettering" by Carl Holmes. This is called a "moderne" style and, with the exception of the truncation of the bottom strokes on the 3 and 5, the letterforms pretty much match an alphabet on page 21.
