After admiring the print for a few minutes I was clueless about the artist. Luckily the invoice was attached, and I was able to research the gallery and print title.

Turns out its by famous animator Lou Romano who according to his wiki page:

He did design work on Monsters, Inc. and The Incredibles, and he provided the voices of Bernie Kropp in The Incredibles, Snotrod in Cars and Alfredo Linguini in Ratatouille.

In 2000, Romano joined Pixar as the production designer of The Incredibles, for which he won an Annie Award in 2005. His artwork has been exhibited at the Museum of Modern Art and the Gallery at The Metropolitan Opera in New York City and has been published on the cover of The New Yorker.

I'm really happy with my gift and I know my son will to after I get it framed. Thanks!!!
