I recently noticed that there are two versions of the famous Queen Mary launch booklet. On one, the ship is referenced as the launch of the 534 on the cover and the other as the Queen Mary. The contents of each is not identical either. The Queen Mary version has tipped in photos of the actual launch and the 534 version has different pre-launch tipped in photos on those pages. I imagine that the 534 version was available before the launch and the Queen Mary version available after the day of the launch. Is there anyone out there who can verify this or provide any additional information?
