White Mat board, also called passepartout, that fits in a frame sized 27 ½ x 39 ¼ ". The opening in this Mat board is 19 1/3 x 27 1/6 and fits a poster sized 19 ¾ x 27 ½ ".

Using a Mat board will elegantly frame and accentuate the design of the poster. A mount can provide balance between the poster and frame, but can also be used to create contrast. The white Mat board is pure white and true to color, including the core of the Mat board. The color of the paper is an exact match to the paper used in our posters. The paper is acid-free.
