RARE Vintage OLD SPARKY ELECTRIC CHAIR Color Change Mug Ohio Corrections & Rehab

This mug was part of a limited production and was only available for ohio corrections and rehab employees for a very short period of time. Very few are likely to still exist, with only one other example to be found. Mug is dark when cold, obscuring the chair. When hot, the chair is revealed. The liquid needs to be very hot to show the design. Hot water was poured directly onto the front for the photo to show the full design. DO NOT MICROWAVE. This mug is in display/collector's condition.
