Old lego set 1950s or 60s? TABAC and/or BAKEREI (from Europe)
The set(s) in question are likely two versions of set 1210 Small Store, released in 1955, or 210 Small Store, sold in 1958. They were available in a number of languages and with a variety of store names. "Tabak" means Tobacco in both Dutch and German. The Dutch word for bakery, however, is "bakkerij", while in German it is "Bäckerei". "Bakerei" is only used in Basque. Most likely, your father had two copies of the German versions of the sets.
