The church in the drawing does bear a striking resemblance to Jeff Ave Pres. However the details are way off from the actual detail of today. Jeff Ave Pres is credited to Writ Rowland as the architect when he was with Smith, Hinchman and Grylls before heading out on his own. Perhaps this is a left over presentation board from a failed bid by Jerome Darling?

Is there still a High street in Detroit? I found a record in 1920 of Jerome Darling building/pulling permits for a 3 story mercantile which could be the building on the left.
