Me too. I usually buy everything blatt-wise, and have labelled plastic carriers in the loft from every successful season - as if being a Red is not a mark of success on its own - including 30 April 1967, my first trip to a Hampden cup final. These two will join the archive.
When purchasing the pair in Big Tesco, I turned every tabloid with its back page featuring The Only Event Of The Weekend round to commemorate our triumph. I also concealed the Times, the Telegraph, and other unworthy news sources using the same system.
Neither Asda nor Tesco seem to have stocked hun and tim birthday cakes since the campaign on one of the former sites was successful in guerrilla-raiding said supermarkets and inflicting damage on said cakes whilst picking them out to inspect them. I checked anyway.
