Issued with the comic ADVENTURE, in March 1934 this set includes the rookie (or quasi rookie) card of MATT BUSBY, great player and legendary manager at Manchester United.
Full set of 52 "Hunt The Cup" football cards, issued in March 1934. As well as an early card of Matt Busby, possibly the rookie single of Busby, possibly not (see BDV cards). No one knows for sure because BDV cards were issued 1932 through until the eve of 1937!
In all you get 53 cards - 1 duplicate plus 52, full set.
