From Top Trumps
Grandmamma is the least known about
STT. The
STT is for the
Roald Dahl Goodies and Baddies pack. It was only given out, free, to Scouts at the Giant Sleepover in 2004. Very few of these are in circulation and they are difficult to obtain even through online auctions. Apparently even the owner of
Winning Moves,
Tom Liddell, does not have a copy of this card. It is thought by some members of the Top Trumps forum that the Grandmamma was never actually released, and that none are in circulation.
Tom Liddell has refuted this belief. However no information other than a blurry preview of this card exists. The Grandmamma card is often spelt as "Grandmama" but this has been disproved and it has officially got a double 'M.'
