The publication, "Nigeria: 20 Years of Patchy Democracy", will be on sale across Nigeria and abroad from June 12, Nigeria's new Democracy Day.
The 188-page magazine features an incisive front-page column by the Catholic Archbishop of Sokoto Diocese, Hassan Kukah, and exclusive interviews with the three living presidents of Nigeria under the dispensation.
This is one of the rare occasions President Muhammadu Buhari has spoken exclusively to a Nigerian medium since he took office in 2015.
This is also true of former President Goodluck Jonathan who is also giving his first of such interview since he left office the same year.
