From 1911 until around 1916, Homer Laughlin made two sets of decorated salad bowls: The "VX" series and "S" series. The bowls were decorated with large floral decals meant for specialty ware such as serving bowls, platters, and jugs. Such decals were not used on sets of dinnerware. Any bowl could be used from an existing shape which would include The Angelus, Hudson, Niagara, Genesee, Empress, and Republic or a specialty shape such as Tioga from decorated specialties.
The decorated salads from this time period are rather hard to find. Most likely they were heavily and didn't survive. Salad bowls from later years, particularly those from the 1930s to 1950s, are rather common and can be viewed here.
