The widening to base mug, is similar in shape to mugs commemorating George Holyoake and Co-operative Society establishments at Sunderland and Ryhope (Silksworth branch). http://www.unitedcollections.net/co-operative-society.html The straight sided, smaller mug seems to be less common. Apart from the added colour the base advertises "J. WHITTAKER FRUIT PRESERVER SUNDERLAND"
Both mugs have distinctly shaped handles.
Sunderland Museum dates similar mugs as circa 1890.
