I have several Lane Rhythm pieces -- Dining table, four side chairs, sideboard, hutch, and most recently, a side table in rough shape. I don't know who designed the group, but I have found a little bit out:
You can read the date of manufacture in the serial number. Just read it backwards. My side table then was made 4-4-64, well before the late 1960s, so Aidrian Pearsall is thereby eliminated, as he'd have been busy designing for Craft in 1964.
Finally, I've attached a screenshot of a scan of the info card that someone uploaded to Facebook.
