Felix the Cat - Pat Sullivan Signed sketch circa 1922 Auction

Greetings!
I have a rare original sketch of Felix the Cat drawn and signed by Pat Sullivan, it was given to a family member around 1922 who used to work at a Hotel in New York city, where Mr. Sullivan used to stay. I have decided to auction it trough ebay instead of doing it trough Christie's as it was initially planned. As an animator and a fan of Felix, I would like this sketch to be owned by another fan who can appreciate its historical value.

Feel free to check it out and make an offer.
