Pennsylvania, one of the 13 original colonies, has a diverse terrain, which includes wide stretches of farmland, national forests, and mountains. Philadelphia, the Keystone State’s largest city, displays its rich history in Independence Hall (where the Declaration of Independence and Constitution were signed) and the Liberty Bell, an enduring symbol of American freedom. I think anyone with love for the Keystone State would appreciate this card. All cards are blank on the inside, A2 size, and are shipped with an envelope. They are printed on American-made cream 80lb cardstock and are shipped in a biodegradable clear sleeve with a recycled backing board so that nothing gets crinkled.
