'Henry G. Schultz & Son built many houses in North Philadelphia, including these distinctive three-story houses and many more just like them on Erie Avenue. This row of houses was built in the spring of 1906,' Minardi wrote about the above image, 1620-1642 Erie Avenue, c. 1906. He said the homes, which have amenities such as front porches and bay windows, in North Philadelphia were 'pretty fancy' and were for those in the upper-middle class. He explained that during this period builders advertised their latest residential accomplishment on postcards and then sent them to prospective buyers. 'They never passed up an opportunity to show off'
