They’re familiar sights, or at least they used to be: coin-operated kiddie rides outside stores around town.

Artist and Queens native Conrad Stojak is bringing these nostalgic pieces back to life. His journey began with a simple call to a number on the side of one of these old machines.

“Got in touch with the owner. His business is just slowly going away because people are not using these rides anymore and they are expensive to maintain, so I am working with him to just bring them back to life and see what we can do artistically,” said Stojak, who has also made artwork in the past out of old parking meters.

Stojak is one of 75 artists featured in Nostalgia Palooza, a massive art exhibition at the gallery at Theater for the New City, or TNC, in the East Village.

The show offers a flashback to different times in the five boroughs as seen through the eyes of artists like Pop Master Fabel, a legendary dancer and artist. Fabel’s contributions include images of kite fights, open fire hydrants — once known as Johnny pumps — and the subway tokens of his youth in East Harlem.

“I knew that I had to bring the heat, and as I walk around here, I’m totally in a time machine, where a lot of the work totally brings me back to old school New York, which I miss dearly,” Fabel said.

The gallery is essentially the long entryway to a cultural institution that has been around since 1971, featuring five theaters and a myriad of arts events.

“It’s a nice experience to bring artists together in a nice spot where there is so much energy involved,” said Marcus Glitteris, who has been curating exhibits at TNC for a decade.

Also curating is Robert Fernandez, known as Nova the Wraith, who says TNC is the perfect place for the show.

“There’s a little bit of dust around here. The walls have been marked up and not painted perfectly, but I think there’s something really New York about this and that’s the point,” Fernandez said.

Check out the show through Sept. 18, including the free closing reception.
