Our concierge down below gave us a large bottle of good red wine for my ‘namen-tag.’ This we drank with our breakfast—first time I’d ever had wine for breakfast…The N. Y. Ballet come here Sept. 1, but we didn’t come to Vienna from Hollywood to witness a N. Y. Ballett [sic]!…A ‘large time’ is in store for me at Munich I hear.
