Abstract
A wedge shaped interlayer blank is used in the fabrication of a laminate e.g. a vehicle windshield to provide the subsequently formed windshield with opposing major surfaces that are non-parallel and offset at a predetermined angle such that images from a display source that are reflected off the opposing major surfaces of the windshield are substantially superimposed over each other.
