Shown are three Apothecary measures and a small Apothecary spatula (next image). Both the larger and the mid size measures are etched WHITALL TATUM CO. / PHILA. The smallest measure is etched ARMSTRONG CORK COMPANY / MADE IN UNITED STATES OF AMERICA. The spatula is etched WHITALL TATUM COMPANY / NEW YORK, PHILA. & BOSTON. These are really 'Go With' to a slug plate medicinal bottle collection I have of which the majority of the marked bottles are base embossed W. T. CO. But I also collect glass insulators so WHITALL TATUM COMPANY and it successor are very well represented.
