How do I find information on an artist print "Heart's Desire" copyright 1927?

Question

The mark in lower left corner is a triangle with 'INC.' in the center. To the left of the triangle is the copyright symbol, A, and 1927. At the top of the triangle is 'M'. At the bottom point of the triangle is 'CHGO'. To the right of the triangle is 'P'.

In the lower right of the print is 'Heart's Desire'.

Here's hoping someone has information. Thanks

R. Atkinson Fox print titled Heart's Desire, the print can be found on page 95 of Gibson book on Fox and Thompson prints. Is this it?
