Calendar Medal Giving Calendar for 1951-1978

<< >>
Description
This small perpetual calendar was distributed to advertise Whitehead Metal Products, Company, Inc. It has a square plastic base on which a plastic disc rotates. The disc and base are riveted together at the center. The years 51 to 78 are marked in an outer circular scale on the base, going clockwise. Leap years are in black and a space with a star precedes each leap year. The top of the rotating disc contains a listing of the months, with special sections for January and February of leap years. Five concentric circles on the base are marked with from 1 to 31, suitably arranged with blank spaces. A window in the outer disc reveals five rows of numbers, beneath the column labels S, M, R, W, T, F, S. By lining up a month on the rim of the inner disc with a year on the rim of the outer disc, one obtains a calendar for the month of interest. Or, as a mark reads: SET MONTH UNDER YEAR ABOVE (/) READ DATES BELOW.
Four images of sandglasses decorate the corners of the base. Text on the back reads in part: To foretell Your Future (/) CALL US FOR HELP ON (/) YOUR METAL PROBLEMS (/) WHITEHEAD METAL (/) PRODUCTS COMPANY, INC. Telephone numbers in eight American cities are listed.
