I have a scan of a photo of the hotel taken by Howard Robinson in the early or mid 1940s.  It was published at the time by Norman Lange in some sort of tourist guide and sold out of his store in East Anchorage (today known as Mountain View).  That publication lacked a copyright notice, which means that it's no longer under copyright.  Robinson Studio was purchased by Ward Wells a few years later, which means that the Anchorage Museum may possibly have it in their collections, as they hold the collections of Wells and Steve McCutcheon and possibly other well-known Anchorage photographers of years gone by.
