Nice girls have good manners and Nice frames have good mounts.
Mounts, for the uninitiated, are those bits of precision-cut card that locate an image within a frame. They serve two important functions:
Aesthetically, a mount defines the spatial relationship between the shape of the (internal) image and the (external) frame and Practically, a mount prevents the image from coming into direct contact with the frame’s glass/perspex, which prevents damage to the image and prolongs its life.
