in the 1960s were a variant of this design. These could be adapted to major streets and shopping centers alike, and averaged . Trademark features included a full peaked roof and signage that resembled the then-popular lava lamp, along with a standardized emergency exit. The latter two elements were retained in Acme's 1970s prototype which succeeded many A-Frame units. In turn, the A-Frame's footprint was very similar to Acme's first standardized building model, which had been rolled out in 1955. Expansion and acquisition In 1961, the American Stores company acquired southern California's Alpha Beta chain of supermarkets. Many of Acme's stores in the 1960s and 1970s were paired with a regional drugstore chain, a PLCB liquor store (in Pennsylvania), a Kmart, or Woolco (earlier centers had a Woolworth), and in rarer cases a department store such as Sears or JCPenney. American Stores also bought the Philadelphia franchise rights to the then fast-growing restaurant chain Pizza Hut in 1968. Acme would also acquire a number of stores from Kmart Foods (as did A&P, Safeway, and Kroger); however, in the late 1970s, many recently closed 1950s-era supermarkets in Philadelphia and close suburbs were reopened as independents IGA or Thriftway/Shop 'n Bag. Starting in the 1980s, these independents were overtaken by family chains Genuardi's (later acquired by Safeway and now defunct) and Clemens (also defunct) along with Giant-Carlisle and Giant-Landover in newer suburbs, and modernized Acme, Super Fresh, and Pathmark stores in the city and older suburbs not long after. From 1978 to 1982, Acme acquired many stores during Food Fair's bankruptcy, including both ex-Food Fair (by then known as discount grocer Pantry Pride) and Penn Fruit units. The bulk of these dated to the 1950s. The former Food Fair/Pantry Pride stores were replaced by or remodeled into stores with the standard Acme prototype of the 1970s, as were many expanded A-Frame buildings and a few former Pathmark (these were former ShopRite) stores. Former Penn Fruit buildings, with their trademark barrel roof, could not be adapted to this model. Even many A-Frames were replaced by the often older but larger acquired stores. In the late 1960s into the 1970s, Acme introduced a new brand of stores, Super Saver that were high volume, but were in high-crime and low-income areas. Both chains had the slogan "Acme and Super Saver - you're going to like it here!" The brand Super Saver was retired in the
