The Constitution of the United States was ratified in Philadephia. Imagine they needed a bag of pens to write it.
Pennslyvania is noted for its Penns (William and James), but it's also famous for its crayons. The factory of Binney and Smith, makers of Crayola crayons, is in Allentown.
Imagine a Number 2 pencil inside the bag to remember that Pennsylvania is the second state admitted to the union.
