Are you referring to the "Thayer Drawing" in reference to the one with the drawings showing the sinking from the striking of the iceberg to the last moments of the stern as it sank ?
There in an interesting video on the thread of "Other books before the wreck......" It seems the dawings were not made by Jack Thayer, but by a passenger on the Carpathia , Louis P. Skidmore. He was an artist and reporter who was traveling on the Carpathia for a cruise to the Mediterranean. Apparent he had met Jack Thayer among the many Titanic survivors. Jack Thayer had apparently described the sinking of the Titanic as he observed it and Mr. Skidmore had made the sketches from those descriptions. There are some errors in the drawings. If you will note the "L.P. Skidmore , S.S. Carpathia, April 15, 1915" in the lower right corner of the drawings.
Thanks to Kyle Naber for this information.
Jack Thayer sketched the outlines and descriptions of the sinking. Mr. Skidmore merely shaded them in and added some detail and took the credit for their publication as a well known artist. The credit should really go to Jack Thayer for sketching the originals and descriptions.
The newspapers gave credit to both men for their joint work.
The original sketches and outlines probably looked like this before Mr. Skidmore shaded them in and added some detail.
The description below each drawing was also provided by Mr. Thayer and he described to Mr. Skidmore what happened.
The Titanic museum in Pigeon Forge TN had a Ken Marschall original I was pretty starstruck by. Been a huge fan since I was a kid and had never seen one before. It was an imagining of what the stern of the wreck might look like, obviously made before the wreck was found, looking all pristine and with the port side propeller completely out of the mud. Too bad the stern doesn’t actually look that way.
They're not easily seen in public, but some of the best paintings of Titanic and other steamers are those by the late Colin Verity. They capture the atmosphere of the age of steam, which in truth was rather dirty and smoky. Google and ye shall find.
