Blue Spruce dinner plate measures 9 5/8 inch diameter. This is the Blue Pine Cone or Blue Spruce Pattern manufactured by Stetson China Co and distributed by Marcrest in the late 1950s. This dinner plate has three blue pine cones sets with blue and grey needles. Very Retro! These were premiums sold at grocery stores where my mother purchased these. There are no cracks, chips or scratches and never used. There is some grazing. The back is stamped: Hand Decorated Made in America Oven Proof Detergent Proof Underglazed with the Thunderbird Mark.
