Arabian Nights Images - Unknown

I can find no credit for the artist for this version of The Arabian Nights Entertainments, which was published by the Hampton Publishing Company, New York, in 1921. It says only "four illustrations in color" for the 300-plus page book, but there is also a fifth image on the cover (left). I'm not sure what this one is from, but it looks rather similar to the "Fair Persian" images by H. J. Ford.

Of the 5 pictures, 3 have women in interesting costumes. In addition to the cover are the following:

This one is from "The Story of the Three Sisters", captioned "The Princess discovered a gold box filled with pearls."
From "The Story of Codadad and his Brothers", this one is captioned "Codadad slays the negro giant."
