What was the name of first comic book sold in America?

The first comic book sold in America is often considered to be "Funnies on Parade", published in 1933 by Eastern Color Printing.

However, the definition of "comic book" can be debated. Some argue that "Famous Funnies" by Eastern Color Printing, published in 1934, was the first true comic book due to its format and content.

Ultimately, the distinction between these two publications is not always clear-cut, and both are significant early examples of the medium.
