Omegna, Italy, 1922-1928.
Cardini toys manufactured only 13 types of toys, of them only three cars, one lorry and a large bus with a chocolate company advertisement. The box that contained each toy, when opened, became a garage, track, hangar, harbor etc., and was illustrated by a famous draftsman of those years, Attilio Mussini.
