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.
These signs were stamped on the back by the L. B. SEELY CO. The stamp on my sign is illegible.
