The player profile on the reverse of the Tony Sealy sticker reads:
“Leicester is Tony’s 6th club following Southampton, Palace, Port Vale, QPR and Fulham. Nicknamed “Jack” (presumably short for “Jack of Clubs”). Busy, bright attacker, who can play anywhere along the front line, or even in midfield. Cost only £50,000 from Fulham, and could become a real snip at that price.”
This sticker of Tony Sealy, from the 1986-87 season, appears to be from a collection by a short-lived publisher called New Generation, possibly as a collaboration with the Daily Mirror or The Sun newspapers.
