Double cobweb valentine with Venetian scene

Cobwebs—also known as beehives, flower cages, or birdcages—are a rare example of a mechanical or movable valentine consisting of a minimum of two layers of paper. First, a web or cage would be cut from a piece of paper by making a pattern of concentric circles, leaving attachment points at regular intervals. In the center of the spiral, a delicate thread would be attached and its outer edges would be pasted directly on top of a second sheet on which an image or message would be written, painted, or printed. As a cover, the cobweb formed the perfect sanctuary to enclose a private message that could only be revealed when the recipient of the card carefully pulled up the thread, causing the concentric circles of the web to rise and magically expose its hidden compartment. The concept of secrecy and the element of surprise frequently recurs in valentines, as they speak to the intimacy that has always been a part of the language of love and is one of the reasons why the cobwebs were so popular.
