I seem to be striking out today.

The stamp illustration I posted earlier is the Dornier Do X:

The Dornier Do X was the largest, heaviest, and most powerful flying boat in the world when it was produced by the Dornier company of Germany in 1929.
Obviously, much earlier than the Howard Hughes' Spruce Goose. Just wonder if this might have been used as a prototype for the Spruce Goose, as there are some distinct similarities.
