Framed PBKC Invincible Ad National Cutlery Co

Neat little framed original clipped magazine advertisement for the Press Button Knife Co INVINCIBLE automatic knife. The ad measures approx 3x5 inches and is in a nice glass front wood frame. It mentions the National Cutlery Co of Walden, NY, which must have been a marketing name used by Walden Knife Co, where the PBKC knives were made. Very interesting ad that features the knife at 50% scale and it sold for 90 cents at that time! It does have an easel so it could either be hung on the wall, or displayed on a shelf or desk.
