Vintage Wood Hangers: 2 Combination Suit + 1 Shirt + 1 Pants/Skirt - $16 (Williamsburg)

These are my dad’s.
There are four hangers in total.
Two are combination suit hangers with an attached pants/skirt clamp hanger.
One is a shirt hanger.
One is a pants/skirt clamp hanger.
The combination suit hanger with the advertisement is probably from the 80s, or possibly even the late 70s.
The other combination suit hanger is probably vintage from the 90s or earlier, but I’m not sure.
I suspect it is because hangers from the early 00s were just made differently.
The shirt hanger is definitely vintage because of the shape and the hook—maybe from the 80s, if not earlier? I’m guessing that the pants/skirt hanger is from the late 90s, but I’m not sure about that either.
The metal clamping piece on the second combination hanger is crooked, but still functions normally.
See photos for the front and back of each hanger.
