True Comics #52

True Comics #52 is an anthology featuring multiple factual stories. One story chronicles the history of sound in motion pictures, tracing Thomas Edison's early development of synchronized sound in the 1900s through the Warner Brothers' successful introduction of synchronized sound with "Don Juan" in 1925. Another story documents speedboat champion Gar Wood's racing achievements, including his 1931 Miss America IX boat's record-breaking speed of over 100 miles per hour and subsequent victories in the Harmsworth Trophy races. A third story recounts Amelia Earhart's attempted transatlantic solo flight on May 20, 1932, during which her aircraft developed a cracked exhaust manifold, forcing her to land in Ireland after crossing the Atlantic.
