Newburyport Five Cents Savings Bank is supporting an effort to restore and preserve the Yoken’s sign, a historic landmark, to its original condition and reinstall it on Route 1 in Portsmouth, N.H. For more than 50 years, the sign was the “go to” landmark for New Hampshire seacoast-area residents and tourists. Air Force pilots used the sign as a dependable landmark while flying into the former Pease Air Force Base. Motorists used it as a directional beacon. Visitors used the famous sign to identify Yoken’s Restaurant and conference center. The bank is asking community members to endorse the sign project by signing a petition; all costs associated with the restoration and preservation work will be paid for by the bank and 4 Amigos LLC of Hampton, N.H., the developer of the Yoken’s Commons retail block that sits on the site of the former Yoken’s restaurant.
