A keystone flag for the keystone state

This is my flag redesign for Pennsylvania, also known as the Keystone State. This is probably one of my favorites.

Symbolism

• The general layout of the flag (a tricolor with three white icons on the center stripe) comes from William Penn's coat of arms.
• Gold and blue are Pennsylvania's state colors. The white stripe is there for visual variety.
• The icons in the center are keystones, representing Pennsylvania's aforementioned nickname.
