Key Features

• Tempered glass front for scratch resistance and true clarity
• Solid wood border in a flat black finish, 1.5 in. wide and 1 in. thick
• 2 included mats: 1 with a 16x16 window and 1 with a 14x14 window
• Mats are acid-free, lignin-free, bevel-cut, 4-ply alpha cellulose for archival-safe display

4 Ways to Display

1. No mat: displays a full 17.5x17.5 in. image, ideal for 18x18 square posters
2. Double matted: layer both mats for a framed 14x14 image with a classic double-mat reveal
3. 14x14 mat only: displays a 14x14 image with a wide single mat border
4. 16x16 mat only: displays a 16x16 poster with a clean single mat border

Mats overlap the artwork by 0.25 in. on each edge, so the viewable area is 15.5x15.5 in. with the 16x16 mat and 13.5x13.5 in. with the 14x14 mat.
