I recognized Bjorn Wiinblad's "King's" and "Queen's" prints in Better Homes & Gardens, 1960 "Decorating Ideas" issue (see my previous post today). It appears that the home owner decided to crop the pieces to fit the frames (unless they came that way; which is unlikely). The prints were designed in the early 1950's.

Here are the same prints uncropped. They are quite large measuring 68.3" x 25.75". The above set was available for $3,250 at the time of this post from Assemblage LTD.
