A great space, a desirable time, smart people and did I mention exceptional material. As wealth has been concentrated, the value of association copies and impeccable material has also increased. The internet has turned out to be both the dealer’s and collector’s friend. But buying and selling precious material is still a person to person process and shows are a vital part of it. The NYABF brings all the these elements together.
Over the upcoming four days - April 3-6, there is the opening night cocktail party (Thursday 5pm-9pm), then the first full day on Friday, the 4th, with almost two hundred dealers, drawn from worldwide, who are there to explain what they are offering, its importance, rarity and issue points. Expect crowds!!
On Saturday the day-trippers arrive. Not everyone has big bucks to spend and dealers know that, even Sequoias started as sprouts. Most exhibitors seed their mines with appealing material that is quite good that can be sold for very reasonable prices.
When you want to fill your mind there are three lectures on Saturday. All events are free with fair admission and will be held in the Armory's Colonel's Room. Please note that admission to these shows will be granted on a first-come, first-served basis.
