It is funny how Hollywood sometimes conforms itself to star, and in 1983 it made way for Eddie Murphy to shine in the film Trading Places. In the background is the flag of the 'Heritage Club' of Philadelphia. It is a horizontal tribar of green, yellow, and green.
The fictional Heritage Club of Philadelphia has a flag flying from the side of the building. This movie plays the rags to riches theme, but also riches to rags, and makes a statement on high society and the city poor. It is classic 1980s movie that pulls hard punches, and not afraid to show some the lewd humor of the time.
In reality this show is a complete fantasy, yet is grounding in reality. It is an absurd plot, but the super rich are often an absurd bunch, who are willing to spend money in absurd ways.
In this shot the Heritage Club flag is to the left of US flag.
