Shipping Slaves, Lagos, 1851
“Charles A.Gollmer. His Life and Missionary Labours in West Africa” was published by Gollmer's eldest son in 1889. This work uses many of the “Missions Bilder” images. Some have speculated that that “Missions Bilder” might have been written by Gollmer because he was a German missionary who worked with Crowther on the Yorùbá language translation of the bible. “Missions-Bilder” was published some years before Gollmer died, he was already retired and back in London.
See "Africa," Missions-Bilder. Vol. 3. Calw & Stuttgart: Bereinsbuchhandlung, 1864-1880.
