Don't worry--this isn't another odious "gun buyback" program where some anti trades you merchandise gift certificates to "get guns off the street." It's an ad in the September 1955 issue of GUNS Magazine placed by the National Camera Exchange of Minneapolis, MN, which would sell you a gun as well (looks like they're out of the gun trading business--oh, that's right, the City of Minneapolis is currently harassing The Last Gunshop out of existence).
That's not all that's changed since this issue was printed.
Take a look back at a different time. Enjoy.
