Bjorn Wiinblad art pottery Enormous centerpiece from 1969 - unique

Bjorn Wiinblad art pottery, very large platter. It is unique and was produced in 1969. Measures 66.0 by 58.0 cm. The platter was born with a firing crack going half around the inner rim of the inside "bowl". It was then attempted to be remedied, but there is a slight colordifference. Otherwise perfect condition. On the back is glued a piece of cloth to protect it from scratching any surface.
