yup from what i can see but ye i would have thought that too.
Heres the bit from ebay
Original piece of U2 stage costume as worn by Bono, designed by Walter Van Beirendonck! I won this item in summer, 1997, in a competition held on the Radio One Jo Whiley lunchtime show. During an interview, Bono offered to donate one of the Musclemen T-shirts he had been wearing on stage for the ‘PopMart’ Tour, as a competition prize: and this is it! During the interview, Jo Whiley and the band joked that the garment would smell sweaty, but it is in perfect condition. It hasn’t seen the light of day since Bono handed it over! But it shouldn’t just languish in a wardrobe, so I have decided to sell! These shirts were made only as stage costume to fit Bono’s exact proportions and were NOT available as tour merchandise! This, therefore, is a unique opportunity to buy a bit of U2 history. So iconic is this garment that the cartoon Bono even wears one in the U2 episode of ‘The Simpsons’! All stage costumes for the ‘PopMart Tour’, including this top, were designed by cult Belgian designer Walter Van Beirendonck As you can see from the photo, it has stitched in, an authentic label reading "W & L. T." (Wild & Lethal Trash) which is the name of Walter Van Beirendonck’s clubwear range. It also reads ‘KISS THE FUTURE’ and carries another little tag which says ‘U2*POP’ A label inside says 95% cotton 5% Lycra. It is very clingy and has a zip along the left shoulder to make it a snug fit. The muscles are printed on top. Even if you aren’t a U2 fan, this is an astonishing piece of costume. Slip it on and admire your transformation into an obscenely fleshy Muscleman. Bid now for the chance to impress your friends with an instant six-pack!
