Miltiadsis Thon was a Greek artist of German descent. He was a descendant of Karl Christian Friedrich Thon, a Bavarian, who settled in Athens in 1833 when he arrived as a member of the court of King Otto.
These hand-colored lithographs appear to have been part of a larger set. Lithographs in sets or otherwise were very popular in 19th century America and the drawings for these images was probably done with the intention of selling them as prints. They refer to incident known as the Whaling disaster of 1871 off the northern Alaskan coast in which a fleet of 33 American whaling ships stayed were trapped in the Arctic ice in late 1871 and subsequently abandoned. Amazingly, no one died.
Please note that in my area where people went whaling from in the 19th century we regard these as history. I know depictions of whaling are not seen like that everywhere. However these images depict no actual whales, that and the ocean won.
