Tenggren goes comics

Here's another finding  from the vault of Kerlan Collections in Minneapolis: a comic strip by Gustaf Tenggren! It covers some thirty pages and I have a vague memory from seeing this in some old clipping from The New York World Magazine. Any information on the origin of this comic story is welcome!

It's not a proposal or a dummy, since every page is thoroughly sketched and cleaned up in ink, although the text is left out for the paper to fill in. The cartoon is a fairy tale kind of story about a selfish king. It's probably made in the late twenties, when Tenggren had some other commissions for The New York World Sunday Magazine. It resembles the style in Mother Goose Book from 1928 or Seldom and the Golden Cheese form 1933. Just imagine what stories there might be, had he made more of these.
