I just obtained an album of boxing cards from Sweden. It shows Braddock as world champ and Louis as a contender. Also has a card of Barney Ross in it as welterweight champ. It has a card of Jackie Brown as a bantam champ; he lost that title to Benny Lynch in September 1935. It also does not mention the 1936 Louis-Schmeling fight though it does mention the Walker-Schmeling fight, which took place in 1932. The cards are about the size of 1952 Topps baseball cards and are paper-thin. They are very firmly glued down so I cannot tell if they have printed backs. The publisher is known for a 1936 Olympics album.
Based on the content I'd say it is a 1935 issue and has 'rookie' cards of Louis and Ross. Here is the cover
