摘要

A novelty calendar which can be prepared by a home computer, has a custom printed background sheet over which is applied a cover sheet with a pattern of windows closed by flaps and secured by adhesive strips around the edge. The user prints a single large image onto the rear sheet and this is progressively displayed as the windows are opened, e.g. an image of a holiday destination. Alternately the windows can display smaller single images.
