Will It Fit, poster. Color photography of blue and white flower petals with graphic elements in the motif. The poster has a white surface around the image, which highlights the subject. If you choose a frame and mat in the same size as the poster, everything fits together perfectly. The mats will not cover any of the image surface as they are perfectly matched with the same width as the white surface of the poster. Frame and mat are not included. Printed on matt uncoated environmentally certified paper like all our posters.
