The shop and its fittings hardly changed in all of this time. The 34 decorated canisters containing the tea are the originals, said to have been made by the tinners of Bradley - "the best in the business" - and were japanned and decorated with the flags of all nations. One showed the flag of the United States, then properly showing 20 stars. The only time at which the US flag had 20 stars was from 1818 to 1819. This might, give or take a few years, show the date these tins were made.
