Memphis Furniture Desk

Hi! I just bought this beautiful desk. It has a stamp that has a pyramid and says, "Memphis Furniture" on it. The only thing I found online was a short Wikipedia article about the company and that it shut down in 1983. I'm not a collector, but I tend to like antique furniture. I have no idea about this desk. The person I bought it from says it was given to her husband about ten or so years ago and was his grandparents for decades. I don't know what year this desk was made or any info other than what I just shared. I would LOVE to find out how old this desk is. :) I'm assuming maybe the 1950's or 60's, but I know nothing about furniture. Any help would be greatly appreciated! Thanks!
