"Still lifes" postcards with table lighters, 1969

Here is a quite interesting series of three postcards designed and printed in West Germany between 1969 an 1971 by Krüger. The still life photos share similar elements, among others: flowers, alcohol, cigars/cigarettes and... lighters: (1) Erhard (Schwäbisch Gmünd) und Consul gas table lighter produced since 1968. (2) Esprit pocket lighter produced since 1950. (3) Any ideas?
