A tamper indicating, multi-layer strip has an upper layer of translucent or transparent material, a tamper pattern-forming layer beneath the upper layer, and a lower, adhesive layer for securing the strip to an item to be protected. A layer of imprintable material which is of area less than that of the upper layer covers part of the upper surface of the upper layer to form a signature-receiving area. The tamper pattern-forming layer is designed to be activated to reveal a tamper pattern through the upper layer when the strip is peeled away from an item to which it has been adhered. A signature is applied to the imprintable material layer prior to application of the strip to an item to be protected, making unauthorized duplication difficult, if not impossible.
