Save the Historic Frisch's Mainliner Sign

The American Sign Museum is proud to have acquired the iconic Frisch's Mainliner sign, a true gem in Cincinnati’s rich history of mid-20th century signage. This sign, a symbol of the beloved Frisch’s Big Boy franchise, has long been a nostalgic reminder of the city’s vibrant past and its unique contributions to American diner culture.

However, restoring this significant piece of history requires substantial work. The sign has weathered many years of exposure to the elements, and before it can be displayed in all its glory, it needs careful restoration to ensure it remains a lasting testament to Cincinnati’s history. The ASM will seek out vintage sign components that will be similar to when the sign was unveiled 70 years ago and restore the neon sections. A new steel structure and internal electrical work will also be required.

The Mainliner sign, with its bold, colorful design and unmistakable charm, has captured the hearts of generations of Cincinnatians and visitors alike. As one of the most recognizable pieces of the Frisch’s legacy, it holds a special place in our collective memory. By bringing this historic sign to the ASM, we ensure that its story—and the story of the era it represents—will be preserved for future generations to appreciate and enjoy. Your gift will be a contribution to restoring and relighting this sign to its full glow.

If the goal to restore and relight the sign is met, the ASM’s stretch goal will be to fund an oral history project to record the public’s memories about this sign and others in our collection.
