Girl with book (Katchoo?)

Baltimore Comic Con 2024
I'll admit that I'm not very familiar with Terry's work but I saw this piece and it really spoke to me. Not sure if it's Katchoo or not for sure, but very sexy regardless.
Then, when I was buying it, he asked "What book is she reading?" She was holding a blank book and I replied that I didn't know. He said that he had decided to leave it blank and ask the person who bought the piece what it was. I then replied that since she was wearing a Wonder Woman t-shirt, it was a Wonder Woman omnibus. He then penciled it the cover while I watched. I have to say, that's one of the coolest extras that I've gotten!
