Invites feature an awesome comic book-style image of the Man of Steel with a You’re Our Last Hope! message. The inside of the card has spaces for party details. After the party, send each party guest a thank-you note featuring cool comic book graphics and a You’re a hero! Thank you! headline. The postcard-style thank yous are the perfect end to your Superman birthday party!
