[1][2] Morgan was a good friend and colleague with L. Frank Baum and shared a studio with William Wallace Denslow,[3] both joint creators of The Wizard of Oz.

Morgan provided pictures for Baum's American Fairy Tales (1901), and illustrated The Woggle-Bug Book (1905).

[4] By one account, it was Morgan who introduced L. Frank Baum to Paul Tietjens, the composer for The Wizard of Oz and other stage projects.

[5] Both W.W. Denslow and Ike Morgan were influenced by Japanese woodcuts on French prints.

Morgan was commissioned often for his paintings, theatrical posters and magazine covers.
