Black and white glossy photograph of four Oakland Oaks baseball players all leaning over to catch the same incoming ball. All gloves and hands are reaching out and everyone's eyes are focused on the ball. They are in white uniforms and dark caps with the "O" insignia on jersey and cap. They are standing on a baseball field and there are bleachers in the background. Caption affixed to back reads: "This quartet of ball players gives the Oaks as fine an infield as there is in the Coast League. Left to right, they are Vic Picetti, 17-year-old first baseman; Gabby Stewart, second baseman who was with the Phillies in '44; Shortstop Jake Caulfield and Third Baseman Chet Rosenlund. They all pack a heft punch at the plate.--Tribune photo." Sections of the photograph have been outlined with white or black ink to form highlights and shadows for reproduction purposes.
