They are ideal for displaying sports jerseys, uniforms, costumes, concert t-shirts, textile artwork, or any meaningful clothing and keepsakes. Designed and made in Canada. Additional Information Gallery Frame vs. Regular Frame A gallery frame is generally deeper and thicker than a regular frame. It can accommodate both gallery-profile and standard canvases without the artwork extending beyond the back. Gallery picture frames with glass also provide more depth and create a stronger dimensional effect on the wall. What Is a Mat? A mat (mat board) is a cardboard insert with a central opening that creates spacing between the artwork and the frame. It is used for paper-based artwork, not canvases. When a mat is included, glass is typically added to protect both the artwork and the mat. “Acid-free” or “conservation” mats indicate archival quality, helping prevent yellowing and long-term damage to the artwork.
