I never released the stuf on the back spelt out PWEI...I changed one of these for the bootlegs we did to ensure it was different to the 'real thing'...which means it might not look like PWEI...will have to look and see.
I've had a look at our 're issuesed' INCREDIDBLE tees and the top logo I changed looks sort of like a P or at least as much like P as the original ones look like WEI...so that's OK then!
