This transatlantic cover is a bit faulty with some wear and tear around the edges (like me)!
Still it is impressive since it has four Pan Am issues on it including the elusive 8 cent!

The registered letter fee was eight cents in 1901, and the letter fee to Germany was
five cents, so a total of thirteen cents was paid on this cover with one 8c, the
two 2c and one 1c Pan American stamps.
The eight cent stamp shows the canal locks at Sault de Ste. Marie. The locks were a
spectacular engineering feat at the time. They stimulated economic growth in the
Midwest by providing navigational links for shipping between Lake Superior and
Lake Huron, and thus established a trade route to the rest of the Great Lakes and
to the Atlantic Ocean.
