Hi Donna, I just found your blog via Urban Reviews. I didn't realize there were this many books on the market with similar covers (the one I did take note of was Crabs in a Barrel/Tastes Like Chicken). As a self-published author, I wonder if it's harder to find that someone else is using the same stock photo. I know that as I looked for a cover for my upcoming novel, I found that several images that I liked had already been used so I passed them over. I do know that there are several versions of the photo that I used on my poetry collection although I've not found anyone else using it - yet. LOL Interesting topic.

I found book covers that used the same model for other book covers
