Venetian Blinds of Steel (Oct, 1937)
Venetian Blinds of Steel
Bullet-proof steel protection for bank tellers, developed along the principle of Venetian blinds is the invention of J. A. Boivin, Quebec, Canada.
The blinds resemble ordinary types, but pressing a button on the floor instantly encloses the lucky teller in 93 square feet of invulnerable steel, 3/16″ thick.
These photographs were taken in the Caisse D’Economie in Quebec, and show how the “bandit” is foiled. No mention was made of what would happen if the pistol were jammed between the strips,
