P. Adolphus Marke was the editor-proprietor of 'The Mirror'. The weekly paper started publication on December 17, 1887 from Broad St, Lagos. However, it only lasted for a year as it closed its editorial offices in 1888.
Prior to entering the paper business, Marke was a local agent for a British firm. He is considered an entrepreneur who found a way to publish a weekly paper cheaper.
