Bonnie, here are a couple of ideas to try: Use a picture of a trumpet, or a bugle, and retouch the artwork, If you make them small enough, they will look a lot like a trombone anyway. OR find a copy of the album "The Music Man" and scan it in, if you have a scanner, I think it has a picture of trombones, if my memory is correct, I am not sure if it has 76 of them. What will you do next year, "77 Sunset Strip"? Good luck, Ken B.
