Abstract: A composite sheet structure can be used as an advertising page, the composite sheet structure having a sample of micro-encapsulated material applied between two opposing layers of material and attached to a carrier sheet. The composite sheet structure is constructed so that the sample can be removed from the carrier material, sampled, and optionally replaced on the carrier. The present invention also relates to a method of making such a composite sheet structure, such as can be used, for example, as an advertising page in a magazine or other publication.
