"Tapum! The History of Arms", (a.k.a. "Tapum! La Storia delle Armi"), released in 1958, is the first cartoon ever produced by Italian cartoonist Bruno Bozzetto, produced with a makeshift equipment (the vertical movie camera used to shoot the film was made with an ironing board with a camera on it!). It features an ironic look at the history and evolution of the weapons used by the men throughout the centuries, and ends with an alarming prevision: the constant improvement of weapons will be the cause of the destruction of the whole humanity in an undetermined future...
It's a nice cartoon with some very funny gags, and a style that reminds of the one used by UPA in the same period.
And now, for your enjoyment, here are some pictures from this cartoon:
We can assume what the reason of the first fight was: the shining smile of a woman...
It was probably a woman who invented the first weapon: the club…
Here we can see the testing of an armour...
Nothing could ever stop the man...
