Cohen & Lord is a law firm. They were moving to a bigger office. I designed two moving announcements. One was a purely typographic announcement. I made the type actually run out of space on the white paper. On the second announcement, I boxed in the type "We've run out of space" with paintings in the office.
After the move, an open house invitation was mailed out. I used a copper foil on the ampersand between Cohen and Lord. The invitation included a reply card. I put the word "open" on the front of the envelope, for Open House.
