1.25" with backpaper by W&H with large text giving address of their "Philadelphia Office." Under the cello on front center is an extra piece of paper showing triangular design with the words "Love/Purity/Fidelity." At the lower left edge of this there is a very minor 1/8" hairline split in the cello. The surrounding text reads in addition to the group name "Hunting Park/Phila., July 21, 1906." Tiniest bit of blue smudge around the word "Park." Still displays glossy and clean. A rare single day event button. Morry Greener Collection.
