Thanks for sending this. I will print it out in color and put them in frame. I teach a course titled "religion in society." It will be great to have a museum of spirituality in general. There is much to be said and learned, sociologically from these pictures which expresses people's authentic effort to engage with a divine force.
A museum of spirituality and religion can be one place where people can reflect and there is a lot of expert commentary that we can have on this. Will this continue indefinitely in Nigeria or will it change under certain conditions, when things change in the country. Based on one documentary series titled "The Christians," this may not continue after certain fundamental restructuring in the form and essence of society. There is one episode where they showed the relics of Christianity in parts of Britain where it used to be vibrant, but now, little or nothing. Then they proceeded to demonstrate how it is thriving in Africa. The title of the episode in reference is "Missions Abroad."
Furthermore, the American Public Broadcasting Service also some years ago aired a series called' Sacred Journeys" -- http://www.pbs.org/show/sacred-journeys/. Nigeria is one of those countries covered in the long documentary film, which focuses on people's spiritual journeys as it is. The documentary shows that some people approach religion with a functional attitude and so they combine two or three religious traditions in order to make sure that they cover all grounds, in case one does not really work.
Frankly, we need a museum with theses kinds of pictures from different religious and spiritual traditions. It reminds me of Rodney Stark et al's rational choice theory of religion.
