No adhesives have been used. The frame hides the very edges of the poster, but I assure you they're very clean. The only visible flaw is a slight fold/crease that extends through the left foot of the green character to the edge. It's not a tear, nor is it a serious crease.
I've shown the area in a close-up photo - it's not noticeable unless it's pointed out.
