The origin of these two plates is unknown but the designs are identical to the two plates of the same names issued by the Franklin Mint.
These plates have the markings "Dynamic Dish Inc. Hand Crafted Heirloom Collectibles since 1989" on the backs of them. These may have been early official issues of Tanenbaum's works or made by an amateur plate maker.
