Wolf, great name I know I have said that before.
You might like to get this book I have just recieved from amazon. Bibliolife, a company that reproduce rare books. AMONG the IBOS of NIGERIA: account of the curious & interesting habits, customs and beliefs, George Thomas Basden, origanlly printed in 1921.
The few pictures are not that well printed but interesting none the less. Here are two pages from the chapter on weapons, there are no pictures of weapons. I found the writing exciting enough even through 1920s eyes.
