Comic strip of Snoopy and Frieda.
This strip is dated 7-18-1967 and measures 7.5" x 28.5".
As visible in the image, there is evidence of ink imprint and a crease in the center of the strip, which is common for this type of work. There are also two very small coffee stains in the first panel, the largest just under the leaves of the tree which measures less than 1/8" and is visible only upon close inspection.
