It's a wee little pamphlet entitled Who's Who in English Church History, published in 1911, from the "Churchman's Penny Library", and it cost a penny. I don't know what the fleur de lis on the cover is all about, but it's not a Roman catholic publication.
In fact, the advertisement on the inside cover is an appeal to "churchmen" asking them to promote The Church of England Waifs and Strays Society. "Cheques and Postal Orders should be crossed 'London and South Western Bank, Ltd., Kennington Rd. Branch,' and made payable to E. de M. Rudolf."
It's a fun little reference work, with very short biographies of saints through every age of Brittanic Christianity include, from Celtic saints to romanizing Saxons to Reformers to Victorian hymn writers. The content is not as unique or as cool as the volume itself of course.
And I'll tell you what makes it the coolest of all. Check out the video and I'll show you my favorite part of this pamphlet.
