"In Commemoration of the Birth of S. L. Clemens"
This 24-page "souvenir" of Hannibal's 1935 MT Centennial celebration was edited and designed by someone named Braxton Pollard, and published locally sometime after the year's inaugural event, the 15 January illumination of the Memoral Lighthouse by F.D.R. by long-distance from the White House. It keeps its focus on the MT of Tom Sawyer (referring frequently to Sam Clemens as "Tom") and "Old Times on the Mississippi" (though the Clemens family had left Hannibal before Sam started learning the river as a cub pilot), and on old-time Hannibal as Tom's "St. Petersburg" (it shows us the swimming hole, for instance, and only one "slave" is ever mentioned: the girl who rescues "Tom" from drowning on page 8).
It begins with The Cave, which had been charging visitors admission since the 1880s. But as a whole it is not overtly commerical. For example, it mentions the new bridge being constructed across the Mississippi and the "thousands of tourists" who will use it to "cross the nation," but doesn't work very hard to encourage them to stop at Hannibal. It contains no ads, nor any reference to tourist attractions. Instead, it boasts about "shoe factories, cement mills," and other industries, and talks about how Tom Sawyer's "playground" has "indeed grown up" into a "city."
