Tarzan the Terrible was first published by A.C. McClurg & Co on June 20, 1921. The image to the left shows the dust jacket from that book.
Metropolitan Newspaper Feature Service, Inc., a subdivision of Metropolitan Books, published an illustrated condensed newspaper comic-strip version of the story. Rex Maxon did the illustrating. The strips appeared in the paper six days a week, from Monday to Saturday. The series doesn't seem to have run synchronically in all newspapers that carried it. The Worcester Evening Post carried the series from approximately March 1932 to July 1932.
These comic strips were collected by Roland N. Anderson (1916-1982) while working as a paperboy, delivering both the Worcester Evening Post and the Worcesster Evening Gazette. Both these papers were published in Worcester, Massachusetts.
When Ballantine Books republished this book in 1963, it summarized it on the back cover as follows: "Lieutenant Obergatz had fled in terror from the seeking vengeance of Tarzan of the Apes. And with him, by force, he had taken Tarzan's beloved mate, Jane. Now the ape-man was following the faint spoor of their flight, into a region no man had ever penetrated. The trail led across seemingly impassable marshes into Pal-ul-don, a savage land where primitive Waz-don and Ho-don fought fiercely, wielding knives with their long, prehensile tails, and where mighty triceratops still survived from the dim dawn of time...And far behind, relentlessly pursuing, came Korak the Killer."
Inasmuch as the Tarzan series was more a series of illustrated short novels than a typical comic strip, the amount of text in each strip far exceeded the amount of text in other comic strips, and consequently of rather small size, about 10 points. In order to make the material more readable, the strips are presented here in halves at about 50% magnification.
One can jump right into the action at the first strip here. On the left side of each comic strip, next to the title, there is a number which indicates that particular strip's position in the series. Some browsers will display this number in the lower left hand corner of the window frame. If someone quits reading some segment of Tarzan the Terrible before having read it all and then at some later date wishes to return to where he left off, this can be done by entering the number of that particular comic strip here.
