Today is Beer Can Appreciation Day. On January 24, 1935, G. Krueger Brewing Company first sold beer in cans to the public. But the rest is not history, as the popularity of beer in cans grew, and can design improved over the years. On January 22, 1959, the seamless all-aluminum can designed by William Coors made its debut with a 7-ounce Coors Banquet.
