Last week I came across the female of this painting on eBay and received multiple emails about what I thought a reasonable price would be for her alone. First let me say thank you for coming to me for my opinion it is unexpected and really fun to share what I know and have learned over the past 10+ years! Here are a few of my thoughts on this set.
The top set is by far my favorite than others I have seen. I like the realism of the musculature and the soft shading and contours. She has a pretty face and great hair and its pleasant to look and really catch all of the details. The bottom version is to dark and harsh. The skin looks like jerky and the faces are not what I consider to be in the traditional Carlo of Hollywood style. The top set sold at auction for $350 and the lower set for over $600.
The one currently listed on eBay is at $400 or best offer but are asking $75 for shipping which I find high for a single painting. That being said, If you could pick it up for under $275 shipped you would be in good shape.
Keep in mind that this is meant to be a set and when the pair does come along you will most likely want that one as well. In my opinion if you desire to have the pair in the future pass on the one currently listed and hold out for what you really want. It will come along at some point and for the right price.
