There are more than one antiques shows on the weekend of Jan 23-24.
Antiques at the Armory is at Lexington and 26th street. Winter Antiques Show will be held at Park ave and 67th street. Free shuttle service is provided between the two shows. I was told by a dealer friend that the entrance fee to get into Winter Antiques Show is astoundingly high, so I assume that 20 dollars admission fee is a deal since the ticket enables me to touch something unaffordable.
If two shows at two armories are not enough, head to Morgan Library between the two shows. The exhibition of oil sketches and drawings from the Thaw collection starts from Jan 23.
