Deletion of 100 Park Avenue Building

Comment: I'm not seeing how those above links demonstrate the notability of this topic.  The building is the subject of the first article, which is good, but the second one is about the architect and mentions the building only in passing and in a large list of projects (it would make an excellent reference for an article on Layton or Wells).  |Notability guidelines insist on "Significant coverage that address the subject directly in detail."  So far, only the Harlow's Weekly article meets this criteria.  The claim that it was once the tallest building in the city has not been substantiated with a |citation to a reliable 3rd party source yet.  Are there other names this building might have gone under
