The 1920s marked the transition from tobacco cards to candy and food promo issues. Popular sets included William Patterson V145, Paulin's Candy, Maple Crispette, and the legendary 1926 Anonymous Issue. Card designs from the decade often featured elegant BW photos or fine illustrations, accented by simple borders and understated typography. Notable rookie cards include George Hainsworth, Joe Ironstone, and the ultra-rare Hugh Lehman / Hap Holmes from the 1926 Anonymous set. These cards were issued without a manufacturer's name or branding. Anonymous cards are the rarest and most mysterious hockey cards ever produced
