Joe Mercer England v Wales international cap 1938-39, blue velvet, F.A. crest, inscribed ENGLAND v WALES, 1938-39 This is curious, as Joe Mercer did not play in the match v Wales at Ninian Park 22nd October 1938. Perhaps he was a reserve and the F.A. extended the presentation of caps on this occasion.
