Bought this book off an artist on Etsy (the author is the artist), has sketches of fictional fish, the sketches have pencil marks (not finished art pieces are showcased in this book), I did get bored one day and started coloring one of the fish (shown in the pictures above, picture#4). It does have 6 finished drawings in the front of the book (ex: picture#6).
