Oodles of Doodles XXVII

Somehow you've rated a two-for-one special today here at Ernie (Not Bert). You already saw Xavier Cugat, and now you get Nat King Cole. This sketch of Nat comes from The Touch Of Your Lips (Capitol SW 1574, 1961). What more can possibly be said about Nat King Cole that hasn't been said elsewhere? The sketch features a signature, something like Bartell maybe. No luck finding anything on Google with that name though.
