Morgan Library at Grace College has a wonderful artifact that appears to be a notebook with various (mostly) handwritten notes, undoubetdly by Billy himself, that resemble the raw materials and resources Billy used in his earliest ministry days, perhaps as early as the 1890s. It is chalked full with handwritten notes, stats, illustrations, and what appears to be outlines for messages. It is personally inscribed by W.A. Sunday with an address of 64 Throop St. Chicago. The address is interesting because across the street from the home (now gone) is Jefferson Park Church (see Bruns:47).
This Google Earth views shows the site of the previous Park Jefferson Church (8-story red building today). 64 Throop would have been right across today, where a long distribution or warehouse sits today.
Evangelist Billy Sunday (1862-1935)
