I had just posted that I had never heard of the Boardroom Collection, but I just pulled one of my older Hickey Freeman suits out of the closet, and it does say Boardroom Collection. Bought it in the late 80's, early 90's from LS Men's Clothing in NYC. So they are pretty old.
Almost identical to the just discontinued black label "Hickey Freeman Collection" suits. Handsewn buttonholes, armholes, and interior collar and shoulder seams, and some hand stitching in the lapel area to give the lapel a roll.
