In 2021, had the good fortune to come across this lovely, new old sock 16″ porcelain over embossed steel Hunterdon County Route 517 shield. These are the original shields from the establishment of New Jersey’s 500-series county routes in the early 1950s. This one was never affixed to a post and just has some chips probably from being jostled around a bit over the years.. The finish is still bright and shiny.
There are a few NJ county route signs that I would really covet, 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.
