Poster prints are professionally laser printed on matte acid-free cardstock for a vividly detailed image. Poster prints come unsigned and packaged with a sturdy backing, ready to mat and frame. They are offered in two paper sizes: 8.5x11 and 11x17. Image size will vary depending on the image's dimensions. 8.5x11 print images are optimized to fit in an 8x10 frame or mat, with 11x17 prints filling as much of the space as possible.
