A page from a personal autograph book kept by a serviceman stationed in the Panama Canal Zone, with entries from friends and fellow radio operators dated 1939-1940. The use of amateur radio sign-off phrases such as '73's' and 'CU AR' suggests the album's owner was a military radio operator, and one inscription fondly recalls shared time 'in Panama,' offering a personal glimpse into camaraderie among servicemen on the eve of World War II.
