Piedmont Tea

Starting in 1987 or so, Piedmont Airlines acquired some Boeing 767-200ERs and began service from Charlotte NC to Gatwick in London.  This tea container (it still has the original tea bags in it) measures about 4.75″ long, 2.75 deep and about 4″ tall.  It was made in England.  I would expect this to have been distributed around the time of the origination of the service.  Speedbird seen!
