SPO-020 / SPN-3 Football Team Presentation Pictures
Roger Pashby has sent in a scan of the Huddersfield Town card that he bought on eBay - a bargain at £3.06!! I believe that George Hepplewhite joined Preston North End from Huddersfield Town in March 1951, which helps confirm that this card was issued in 1950-51. The same photo was used in the 1951-52 Playfair Football Annual - thanks to Roger's superb website - The Huddersfield Town Collection.
