The yellow building in the reflection is the Sherry-Netherland Hotel on 5th Avenue and 59th Street. The glass building doing the reflecting is the GM Building, one block south between 59th and 58th Street. You can also see the Apple Cube on the bottom right corner of the photo.
I apologize if I have not been visiting your blog lately. It's been a busy week for me so hopefully, I will be able to do some catching up in the next couple of days.
Hope you all have an enjoyable, relaxing weekend.
