This plate does not have a makers mark on it, so it leads me to believe it was made during the 1940's-1950's. Several companies made this pattern from 1880's to today.
This is very similar to pieces made by L E Smith. Smith started marking his pieces with an S during the 1960's. Prior to 1960 he did not mark his glassware. Smith never owned the molds for this pattern, they only had a lease on the molds and contracted with other companies to produce the pieces under the L. There may be a small hairline crack under the plate, it does not detract from piece, (please see pictures # 6 and #7).Please view all the pictures as they are part of the description. If you need additional pictures or would like pictures with color swatches of different blues beside it, just let me know. This would be a great treat for yourself or that perfect friend. This comes from my smoke free/pet free home. Some information on L E Smith and the Moon & Star Pattern.
