Abstract
An advertising or promotional item is made by preparing a visual advertising or promotional message and cutting it into a plurality of separate interfitting pieces, substantially all of which have the same shape and size as at least one other piece. After interchanging the locations of most of the pieces to scramble them and hide the message, the scrambled relationship visual image is printed upon sheet material and then die-cut to form the original message pieces arranged in scrambled relationship, whereby the recipient must rearrange the pieces to discover the hidden, advertising or promotional message. Preferably, the message region is divided into three or more substantially identical sections. The die-cut sheet material may be laminated with pressure-sensitive adhesive to a backing sheet having a release coating and may be applied to or formed as a part of the sidewall of a container.
