Very tough 1952 Knowles Service Station Stockton Ports complete set of (11) cards. This obscure issue is housed in a decorative album. The cards generally present in (EX to EX-MT) condition and are highlighted by the inclusion of Japanese player Fibber Hirayama. The album measures 8-1/8 by 7-7/8" and features striking aqua colors with raised silver accents. The front cover exhibits moderate perimeter wear and superficial staining. The black interior staple-bound pages are tightly attached to the staple binding. This incredibly scarce artifact is for the minor league specialist who wants to view the set as the company originally intended. A company sponsored 9-3/4 x 7-5/8" black-and-white team photo grading (FR) due to residue/writing is also present. Opening Bid $500.
