Don asked whether anybody had ever seen a Giotto Cinelli bike from the 1940's.
There is at least one in California. The headbadge shows a knight mounted on a horse (not only the knight's head like the later Cinelli logos) The cranks are also marked with G. Cinelli and once again the knight mounted on a horse. According to Andrea Cinelli (son of Cino), who spoke to his uncle Giotto for confirmation, there were very few frames built with the Giotto Cinelli name. You can however see a photo of an amateur team that Giotto sponsosred here:
