Embossed steel. Embossed outside. Beer. Production period: 1970-1972.
Inscription on cap: along the inner circumference - "Жигулевско б.п. 25к.", along the outer one - "Жигулевский к-т ГОСТ3473-69".
An extremely rare and amusing variation. There is "Жигулевско" instead of "Жигулевское" (the last letter is absent).
