Framed original 1890s Press Button Knife Co Invincible Ad

Here's a little something to hang on the wall for collectors of American switchblade knives, or anyone else who might appreciate an 1890s vintage switchblade ad. This ad is from and 1890s Recreation magazine which used the Press Button Knife Co INVINCIBLE switchblade as a subscription incentive for 3 yearly subscriptions to the magazine. The ad measures approximately 4.5 x 6.5 inches and is in a nice oak 5x7 glass front frame. I authenticated it on the back when I framed it in 2019 and autographed it as the author of the book Antique American Switchblades. It's always interesting to see these old ads and you can have this one hanging in your office, or den, or wherever it can be appreciated.
