The autogiro was not a helicopter, but a predecessor. Its overhead blade was essentially just a rotating wing (often unpowered), unlike the helicopter's main blade that provides both thrust and lift. It could not hover, or take off or land vertically like a helicopter; but it could fly slower than an airplane, and take off/land in much smaller spaces than fixed-wing aircraft. It was also much simpler mechanically than a helicopter. I do not know what publication included this 1932 ad for a Pitcairn Autogiro posted by Vintage Ads, but it must have had wealthy readers, since even a car would have been a luxury for many in 1932.
