First appearence of Disney's Mowgli?

On October 18, 1967 Disneys animated version of the Jungle Book was released. (Exactly 29 years after those model sheets in the last post were OK:ed...)
But observant readers of the Mickey Mouse daily strip already had a chance to see what Mowgli looked like.
In the strip dated July 6, 1966 we see Morty reading from one of his favourite books. And who's on the cover? Ta-da!
Is this drawing of Mowgli, by Floyd Gottfredson, the first of Disneys version to see print?
