24: Blackstone's Illusion Plans

Blackstone, Harry. Four holographic manuscript pages illustrating the construction of an illusion. Blackstone outlines the mechanical operation and construction of an illusion in which a girl, seated in a massive translucent bowl, appears on a bare tabletop. Sketched in pencil in Blackstone's hand, with measurements, details of construction, working instructions, and signed twice by Blackstone on two separate leaves. Poor condition; pages tattered and folded. Should be seen. Unique.
