I've got that shirt safely tucked away in my drawer. Never supported Widnes but that side (1988-1991) was, and still is, the most exciting teams I have ever seen.
BTW let me throw the Oldham "Boddingtons" red and white shirt (Circa 1990-91). It is the best strip bar none IMO. I think they wore it in the 1990 CCSF against Warrington. Any one got any piccies?
