Are you designing a book cover and need a mockup that can showcase it in two various positions? I recommend you this mockup that shows two hardcover dust jacket books.
One is a front view model, and the other one showcases the spine outlook. Both of these books are standing in the middle of this scene.
You can remove the current colorful graphics and add your prepared one instead. by utilizing smart layers, you can change the colors of this book mockup to suit your project better.
