Alaska and placed it in front of her store. The pole served as a marketing tool for the company, as it attracted a great deal of attention. Soon, executives added totem poles in front of every store and eventually adopted an Alaska Native-inspired theme for their stores. Later on, the stores began operating under the name "Tote'm Stores". In the same year, the company began constructing filling stations in some of its Dallas locations as an experiment. Joe Thompson also provided a distinct characteristic to the company's stores, training the staff so that people would receive the same quality and service in every store. Southland also started to have a uniform for its ice station service boys. This became the major factor in the company's success as a retail convenience store. In 1931, the Great Depression affected the company, sending it toward bankruptcy. Nevertheless, the company continued its operations through re-organization and receivership. A Dallas banker, W. W. Overton Jr., also helped to revive the company's finances by selling the company's bonds for seven cents on the dollar. This brought the company's ownership under the control of a board of directors. In 1946, in an effort to continue the company's post-war recovery, the name of the franchise was changed to 7-Eleven to reflect the stores' new hours of operation (7 am to 11 pm), which were unprecedented at the time. In 1963, 7-Eleven experimented with a 24-hour schedule in Austin, Texas, after an Austin store stayed open all night to satisfy customer demand. Later on, 24-hour stores were established in Fort Worth and Dallas, Texas, as well as Las Vegas, Nevada. In 1971, Southland acquired convenience stores of the former Pak-A-Sak chain owned by Graham Allen Penniman Sr. (1903–1985), of Shreveport, Louisiana. With the purchase in 1963 of 126 Speedee Mart (all already open 711) franchised convenience stores in California, the company entered the franchise business. The company signed its first area licensing agreement in 1968 with Garb-Ko, Inc. of Saginaw, Michigan, which became the first U.S. domestic area 7-Eleven licensee. In the late 1980s, Southland Corporation was threatened by a rumored corporate takeover, prompting the Thompson family to take steps to convert the company into a private model by buying out public shareholders in a tender offer. In December 1987, John Philp Thompson Sr., the chairman and CEO of 7-Eleven, completed a $5.2 billion management buyout of the company.
