Memphis Furniture Antique Bedroom Set

I have this antique bedroom set I believe might be a rare item, it has a Memphis Furniture Manufacturing Company Logo stamped on it

from the Pyramid Line... Has the numbers M 1234 stamped on the back as well... It is the dresser, vanity and mirror, and full size bedframe with  footboard and headboard.... Any help on the history and value on this would be great :)
