The Klopsch "Red Letter" New Testament was published in 1899. In 1901 the Klopsch Old and New Testament Bible was published. This was the first English language Bible to be published with the words of Jesus printed in red ink. These Klopsch Bible scans are derived from two copies purchased over the internet. One was owned by George Robert Eads and his wife Wanda Lynn (Jones) Eads. The other was owned by Park P. Stethem and his wife Mabel Louise (Barr) Stethem. I found the YouTube review of the 1st New Testament edition very interesting.
This website reproduces the 1901 Klopsch Bible. This is a window into the world of our ancestors who often had large "Pictorial" Bibles that were crammed full of additional resources. This was when books began making their way into homes through the Colportage distributions. That was a time before radio and television, when books were the main way of getting information before the internet. The Klopsch Bible scans are all here.
