"While I can't identify the source of the above image in question, a quick search on the internet revealed the following similar view. Please note that in this alternative 1881 image by Benjamin Evans, the Mint building at left has the requisite six column facade. Perhaps the undocumented image reflects some artistic license on the part of the artist? The Mint, after all, was not the focus of either drawing. Then again, in the Evans drawing apparently there are four columns of windows on the left face of the church, vs. five on the unattributed view?! Obviously these are two views of the same location, but these differences are challenging to interpret. Did the artists draw what they saw?...or is this evidence of nineteenth century "photoshopping"?"

"... the Mint ... appears in this 1881 Evans watercolor of the Seventh Presbyterian Church, known as Rev. Lord's Church, located below Southeast Penn Square..."

"The second Mint image was drawn by Frank H. Taylor, who did a whole series of Philadelphia street scenes c. 1900. There is a large (complete?) collection of these in the Free Library of Philadelphia. I don't believe they were published at the time of creation but were available on a subscription basis. See Secret History for more on Taylor."
