Is Felix Australian??

On another wall in Surry Hills, a Very Big Felix (and look at that bizarre small sticker in the bottom right hand corner. What's THAT about???)

Some claim that Felix was first by New Jersey cartoonist Otto Messmer. Others say that Felix was the brainchild of Australian cartoonist and film entrepreneur, Pat Sullivan.

Wikipedia says:

"...evidence seems to back up both claims. However, many historians, such as John Canemaker argue that Messmer ghosted for Sullivan. Other historians disagree. What is certain is that the cat emerged from Sullivan's studio. "

Here's a post I made about Felix in 2006
