The Le Domino has to be the coolest ukulele around. They're marked out by their jet black color and the trademark is the decal on the body of a pair of dominoes - some models also have dominoes as fret markers. They were predominantly made in the 1920's and 30's and vintage Le Dominoes crop up on eBay fairly consistantly.
