John A. Whitney, known as the "Dynamite King," was featured in the Portland Evening Express on April 28, 1927, in an article titled "Dynamite King Demonstrates Harmlessness of His Wares If Intelligently Handled." The piece detailed his explosive work across New England and his storage sites beyond the easterly end of the Martin’s Point Bridge. This image shows Whitney’s ship fully loaded with dynamite crates, reflecting the scale of his operation and his confidence in its safety.
