Pete Davidson has been a walking billboard recently, for a sandwich shop in downtown L.A. ... and while he's getting no coins, he's showing lotsa love to the deli and its owners.
The folks at Uncle Paulie's Deli tell TMZ ... Pete doesn't have a stake in Uncle Paulie's, he's just good pals with Paulie, with something in common ... they're both from New York.
Pete was rockin' an Uncle Paulie's hat this week at the Knicks game.
The deli definitely appreciates the support from Pete ... fact is, he's the most famous walking sandwich board in America, and the publicity is worth a fortune.
The Knicks game wasn't a one-off. Pete recently wore a Paulie's hoodie and hat at Nobu in Malibu ... oh, and he ran into Martha Stewart and they posed for a photo.
It's good/great timing ... the deli's opening 2 new shops in L.A. in the next month ... one on W 3rd St., and another in Studio City.
No baloney.
