Several small framed decorative prints can be seen on the living room walls of the I Love Lucy set. A set of cavalry sword men appear on the wall next to the fireplace and also on the back wall on either side of the larger Utrillo picture.

These prints  framed by Borghese are not identical  to those pictured in the screen grab above but they are from the same series of cavalry prints derived from an antique publication of broad sword exercises by Thomas Stephens.
