Pair of Writing Slates with Magnetized Slate Advertisement. Early 20th century. Two chalkboard writing slates with mahogany frames (not gimmicked). [Together with] a framed advertisement for “Campbell's Magnetised Slates". Spirit slates were used by mediums during seances to “reveal" messages from the dead. These were often gimmicked with magnetic components or simply traded out in a moment of distraction. Slates each 9 x 7". Good.
