Wedgwood Blue Jasperware Plate Cream Colored Relief Classical Design. Wedgwood calls this light blue “Cream on Lavender” in their Jasperware line, raised relief on unglazed pottery. Measuring 9.5 inches in diameter, this is their cake plate. Although this is one of Wedgwood’s most popular patterns, it has been discontinued so you have to buy this pattern from private sellers. This plate is in very close, previously used, vintage condition, with no cracks, chips or repairs.
