1) Remove the back of the frame by bending up the "flex points" located around the mat on the back of the frame.
2) Remove the back and front mat pieces leaving the glass in the frame.
3) Mount your Sports Trading Card(s), Comic Book or ATC by sliding them into the pockets of the inner lining as shown in the picture.
4) Replace the pocketed lining and inspect the mounted piece to be sure that the card(s) or comic book is arranged how you intended.
5) Place both mat pieces back into the frame and bend the "flex points" back into place to secure the glass and mat pieces into the frame.
Hang and enjoy....
