The Cartoon Art Museum is accurate to its name. It really is an art museum. Just as an art museum does not talk about how oil painting is done, the Cartoon Art Museum does not spend much space if at all on how cartoons get drawn and inked throughout the years. It showcases cartoons/comics as art, and gives history on each of the artists.
It's fairly small. My group and I read just about every comic and history and went through it in an hour or two.
The adjoining store, which apparently is NOT part of the museum, actually focuses on photography -- which is not to be found in the museum.
