Patent drawing - Betty Boop colored patent Public domain image

Here are the two original drawings that I colored and modified to make this one.

Betty Boop character design, figure 1 from U.S. patent application D86224 "Design for a Doll or Similar Article". The original drawing was published on 9/24/1931, but my colored and modified version of the drawing was done on 2/4/2015.

I colored the original black and white drawing, and I also altered the drawing a little bit. I lengthened the dress. I made the eyes more symmetrical. I shortened the lengthy eyelashes to model them after a more recent drawing of Betty Boop. I added green irises to the eyes which I modeled after a more recent drawing of Betty Boop. I fixed the unrealistic thicknesses of the knee joints. Lastly, I changed the thigh accessory to make it a heart design.
