Actually, Uncle Sam has many versions, not just this one. It is said that he was from 18 century. At that time, the United States was still at war with Britain.

His honest, reliable, hardworking and patriotic spirit is regarded as the American spirit, so it is regarded as a symbol of America. However, another reason is that he worked as a quartermaster inspector in new york and New Jersey, and was responsible for stamping beef barrels and wine barrels supplied to the army. Governor new york showed some people around its processing plant. When they saw the logo of E.A.-U.S on the beef barrel, they asked what it meant. The staff replied that E.A. is the name of an arms contractor and U.S. is the abbreviation of the United States. Coincidentally, the abbreviation of "Uncle Sam" is also U.S., so a worker joked that U.S. is "Uncle Sam". This version is also widely circulated in the world.

But what really made him famous was the cartoons drawn by various cartoonists.

This is a tough battle. Give me the best,,,,,,
