I've recently picked THIS LIDDED JAR up at a yard sale in Ottawa Canada. The only markings are "WILSON" that is Stamped and is also Signed. The Piece is about 5-inches high. Good condition, no signs of damage. I believe it's Ironstone?, with Salt-Glazing. It has a lovely texture.
If ANYONE recognizes the MARK or has any info, etc. it would be greatly appreciated!
