New Jersey’s 500-series county route system, established in the early 1950s, was originally marked by very handsome 16″ embossed porcelain signs. This example, sold to me by a resident of Califon, survived in good shape. I am quite familiar with Route 512; much of it is still a pretty drive today – probably surprisingly so to anyone who doesn’t really know New Jersey.
There are a few NJ county route signs that I would love to get my mitts on, especially in this porcelain form. Passaic County Route 509 would be my personal crown jewel.
From seeing clearer examples on other signs, I know that the blurry stamp on back reads:
L. B. SEELY CO.
Eatontown, N. J.
FERRO ENAMELING CO.
