Sciencfikcio en Esperanto (12): International Science Fiction (3)

Mi enretigis la jenan novelon / I have digitized this story from International Science-Fiction, No. 2, June 1968:

“In 2112,” by J. U. Geisy & J. B. Smith, translated from Esperanto by Forrest J. Ackerman

Here is what Ackerman says at the end about its origin:

This antiquity, written in the year Tarzan was born in the pre-Gernsback prehistoric era of "different" stories and "offtrail" stories and "scientific romances," is from the early literature of Esperantujo (Homeland of Esperantists).

I would like to track down the Esperanto version of the story, if possible. / Mi volas trovi la esperantan originalon de ĉi tiu traduko.
