It has been reported that every piece of Teco pottery was originally marked with a paper label containing the name of the designer and the pottery, as well as the model number and price of the vase. However, it is rare to find a Teco vase today that still retains its original paper label.
Many Teco vases were stamped at least once with the Teco trademark and it is not unusual to find vases double and even triple stamped. Teco was also routinely marked with the shape number in addition to the trademark. Later examples of Teco ware were marked with the word "Teco" in a rectangle. The following photos provide examples of typical Teco pottery marks.
