Blackmon’s The Coming Judgment Day was published in Atchison, Kansas, possibly in the late 19th Century.
We speculate he might be Adventist minister Elijah G. Blackmon (1843–1913), who taught singing in school
(per Findagrave), and is buried in Spurgeon, Missouri. His obituary reportedly appeared in the now defunct Neosho Times, April 3, 1913.
