The 1956 German football championship was the culmination of the football season in West Germany in 1955-56. Borussia Dortmund were crowned champions for the first time in their second final appearance, having previously lost the 1949 German football championship final to VfR Mannheim. Using only the above description and what you know about the world, "There were seven years between Borussia Dortmund first two championship appearances" is definitely correct, incorrect, or inconclusive?
