Here’s an array of True Blues!
In 1929 Parker introduced one of the most sought after of their low-priced school pens, known today by collectors as the "True Blue." This new slender blue and white swirled Permanite celluloid pen was called the "Three Fifty" in early Parker advertisements and the 1929 Parker catalog. The color was called "Modernistic Blue" in 1929 ads and the 1929 Parker Catalog and "True Blue" in 1930 ads and the 1930 Parker Catalog. The earliest Parker advertisement I could find showing this new pen line is in the May 19, 1929 Pittsburgh Sun-Telegraph. The True Blue does not appear in the 1932 catalog, indicating that the line probably ran from 1929 through 1931.
