This is surely the only extant neon Oldsmobile sign in New York City. I almost passed it by without noticing, so seamlessly has it facing into the background of visually hectic Flatbush Avenue, near Avenue D.
It's a beaut of a sign, two-sided and three stories tall. Also, the block at the bottom, by some miracle, works. Most certainly, this was an Oldsmobile dealership once upon a time. The sign also used to be red, based on old photos.
