This series was issued in 1910 as a supplementary series to the original 1909 set of 120, and was designed to take the series up to 282 cards. The backs of these cards state as much, therefore you’d expect to find a further 162 cards, yes? Well, think again…
There were no cards 1-120 because they had already been published as the first issue, so this series picked up the gauntlet with card 121 and headed up towards 282. Except that it didn’t…. Derby County – a football team which would appear in the 1911 third issue – were nominally numbered 274-282 but those cards were never issued, meaning that there are no cards beyond 273 in this series.
