The postcard album contains 75 marine vessel postcards and 39 train postcards collected by Martha Hoffman. The train postcards,
out of scope, have been retained to maintain the integrity of the album. 32 of the marine vessel postcards are of U.S. naval
vessels, 12 are of Bay Area ferry boats and 11 are of steam ships. The bulk of the naval ships were postcards depicting the
Great White Fleet.
