This appears to be a collection of commissioned works, created sometime in the 1960's or 1970's according to the organization's web site. These were most likely done in the later part of that period, as evidenced by the citation on the picture of Lincoln Hall as the "Lincoln Music Hall" the library had already shifted, so this was after 1975 or so. Given this date, the painting of Old North (razed in 1962) was very likely done from a photograph, as the others also may have been reproduced.
