L&M cigarette advertisements from New York City Subway, 1968 or 1969.
L&M stands for Liggett and Myers, later purchased by Philip Morris.
These ads were posted above the seats along the outside edge of the subway car.
They measure 11 inches wide by 28 inches long.
To me, sitting across from them, they were the only interesting advertisements posted,
they gave me something to read and were slightly amusing.
