ABSTRACT:
A fan device comprising two flat leaves inseparably attached to a flat hollow handle that serves as an envelope wherein the folded leaves can be tucked away when not in use. The fan opens for use by telescoping the leaves out of the envelope/handle part way, unfolding them, and then inserting side tabs of the leaves into side slots on the envelope/handle. Top center notches on both leaves are then interlocked forming a rigid plane comprising the two leaves joined to each other and to the envelope/handle to become a unit that is sturdy enough to be used for fanning. The surface area of the fan may be imprinted with indicia, for viewing during fanning or as a display.
