I have heard of black and white cats marked like yours referred to as "Tuxedo Cats". Not an official breed, but a descriptor for the markings. If you search for "Tuxedo Cat" on Google, you'll see many, many like your beautiful cat on there.

Socks Clinton (former first cat) was a Tuxedo. I recall back when the Clinton's were in office, Cat Fancy had a big spread on Tuxedo Cats and a contest for the one that most looks like Socks.

Your cat is beautiful -- is his tummy white, too?
