The Sports & Pastimes series was popular multi-sport theme in the years between 1910-1930, and same artwork was used on no fewer than 12 different sets throughout the years. Card #11 in the series features lacrosse, though the lacrosse card is for some unknown reason #9 in the 1925 Cope Bros set. The card fronts are the same throughout, while the backs feature advertisements for different products and are what differentiates one set from another.
