Looks interesting. Your writer on Philadelphia missed an opportunity to point out the many writing implement historical spots in Philadelphia, including Esterbrook's original location on Arch St., the longtime location of Turner & Harrison on first Buttonwood and then Spring Garden St. (the factory is still there, but now it's four stories), Leon Isaacs locationsn, and other turn-of-the-century steel pen makers, etc...
I keep thinking I'll put together an address list for New York City of past important sites. Most are clustered downtown on a small number of streets. (Maiden Ln, John St., Broadway for the most part)
“When the historians of education do equal and exact justice to all who have contributed toward educational progress, they will devote several pages to those revolutionists who invented steel pens and blackboards.” V.T. Thayer, 1928
