Brand: Adelphia Pencil Co.
Made in: USA
Thus far the only pencil I've seen from Adelphia Pencil Co.
According to public records, Adelphia Pencil Co. first filed corporation papers on May 23, 1928. And no surprise they were based in Philadelphia, PA. In 1932 the company was offering a dozen "good pencils," with name printed in gold, for 50 cents.
