Greetings from the Keystone State

Pennsylvania-themed letter sent by Phillip (the USA). On the envelope, a non-Pennsylvanian wine label, that matches perfectly with Erie Harbor North Pier Light, with an unique design ("the tower tapers from its base to its midsection, then rises straight from there to the top")

Phipps Conservatory and Botanical Gardens in Pittsburgh and a detailed map of the state.

And matching stamps: Erie Harbor Light and the state flag.

A week after this letter arrived, I got this postcard through the Postcrossing site, featuring Erie Land Light another one of the three Erie lighthouses.
