Banksy: That's Not My Art, But You Are Getting Sued

A street artist not named Banksy is suing a company for trying to pass off his prints as Bansky originals ... TMZ has learned.

Eddie Colla claims online retailer Touch of Modern is selling one of his pieces without his permission. Adding insult to injury ... they're hawking it as a Banksy.

The painting does look a bit like the famed anonymous artist's work -- but Eddie says the image is well-known as one of his pieces. He's suing to get Touch of Modern to stop selling his art immediately, and to cough up some dough.

We'd say we reached out to Banksy, but ... y'know.
