The catalog has this
Garden City, N.Y.: Doubleday, Doran and Company, Inc., 1927, copyright 1929.
The whitewasher made sure it was right. Notice N.Y. has a period after both letters. Same for Inc.
The books as presented to the public have this:
Original publication: Garden City, N.Y: Doubleday, Doran and Company, Inc, 1927
Trailing periods have been stripped, leaving N.Y which of course is not what we want on the public-facing page.
