Premier League 2002 - W prefix stickers
Merlin / Walkers Crisps
80 (UK), 84 (Eire)
Sean DeLoughry has reminded me that the Walkers Crisps stickers were to be collected in an album that was included in the centre of the main Merlin album. The four additional stickers issued in the Republic of Ireland were intended to be stuck on the inside of the front cover. The complete checklist can be found here - Merlin / Walkers Crisps - Premier League 2002 - W prefix stickers.
