By the way: In Karen Hearn's book Marcus Gheeraerts II (2002) you will find a series of beautiful paintings depicting pregnant women. (The paintings were not made for amusement. In Gheerhaert's time, pregnancies always were a threat to the life of the mother.)
Back to the comparison: "Do Henry Holiday's illustrations have any meaning?" That is the wrong question. For a lucid artist like Henry Holiday the question was: "Which meaning will the beholder give my illustrations?"
2010-07-24: Today I promoted this image to my set for comparisons which yield strong resemblances. I did this comparison in March 2009. But there still is something new to discover. After more than a year passed by, I spotted another pattern match which is a clear and strong resemblance. I leave it to you to find it too. Perhaps you find even more matches?
