Coronation St Original 90s Reg Holdsworth " A Man of Natural Appetites" XL. Unworm sample from my old office. I used to produce and distribute these in the 90s for Granada TV, back in the days of Reg and Raquel.(I've also got a couple of Raquel shirts)
White XL tee, measures 24" armpit to armpit, chest 48". 
I have more of this design in Grey and possibly other sizes, I've not looked yet, and "Knowledge is Power" shirts. If anyone asks , I'll hunt the rest out. Condition is like new apart from the neck label has faded with age and a couple of washes over the decades
