This is one of Bryan Lee O'Malley's Scott Pilgrim vs. the World band sketches. I have some of the other sketches, too. The originals were acquired for the production, and copies like this one were made and used in the movie.
Sure--I've been getting literally truckloads of stuff from myriad productions for years at the studio. Since the shelter-in-place order, I've been going through more stuff and selling it. Sold the Drummer Unknown a few days ago, but I have a about 3-4 of each one. As I list them for sale (I generally sell them in the big prop group on Facebook), I'll post the pix here too.
