We don’t know what city this is, or even if it is the entire postcard.  On the heavily aged, unused reverse, it looks like this may be half of a panoramic card.  The front doesn’t suggest so.  Either way, the only caption is “No. 103, A.C. Dietsche, Detroit, Mich. and Frankfort, Germany,” with additional reference number 201490.  We’re guessing this is not Detroit.  Grade: 5
