Warwick china was made in Wheeling, West Virginia, in a pottery working from 1887 to 1951. Many pieces were made with hand painted or decal decorations. The most familiar Warwick has a shaded brown background. Warwick's most desirable pieces are those decorated with portraits of monks or American Indians and its vitrified chinaware, an unusual product for a nineteenth-century American company. The name Warwick is part of the mark and sometimes the mysterious word IOGA is also included.
