No, that is not a towel, it is a T-shirt~~

At that time, American T-shirt manufacturers only produced solid-color T-shirts without patterns. The market soon disappeared. People I didn't like this monotonous clothing. Later, after the factory manager finished gardening at home, he took a T-shirt and wiped his face. After wiping, there was a pattern on it~~ He got inspiration from it and made a lot of money.

The pattern in the movie was the pattern on T-shirts that were very popular at the time.
