This unique three-panel barrel-fold mailer was created by The Journal of Joint & Bone Surgery to celebrate their 125th anniversary. Their designer chose a die-cut for the number 125 on the opening flap and an angle cut for the trailing edge which aligns to the left edge of the number five on the front. The reverse of the piece features a mailing panel and CTA. This mailed in a clear envelope, giving recipients a nice preview of the die-cut front of the piece.
