A handicapped symbol holding a trombone?

I saw it once and so did my co section leader. It's exactly like the handicapped symbol ( http://bayviewmerchants.org/blog/wp-content/uploads/2011/01/451px-Handicapped_Accessible_sign_svg.png ) But it has a trombone in the same font. I would really like to find a picture of it so I can put it on the trombone section shirts for my high school
