One month ago today, the Polaroid SX-70 Land Camera -- a camera that TIME's own Harry McCracken called "the greatest gadget of all time" -- celebrated its 41st birthday. When it came out it was absolutely revolutionary, and to get the word out, Polaroid put together a few ads to show off the instant shooter.

If you're a fan of the Polaroid SX-70, this promotional video from the 1970s should stir up warm fuzzy feelings. If you've never used one, watching this might give you a better idea of why so many are obsessed with it.
