Nick, aka Prospero, typically hosts the NYSE, which is one of the marquee Paper events with 10-15 proxies (I forget the specific number allowed and it might change). People have traveled from across the US and even from Europe to Long Island, New York to play in it, which is why this is here as a heads up to those who might want to make plans or take off work.
Historically, the event has been $100+ entry fee with prizes of the Power 9, though with the cost of Power increasing I think there was talk of switching to cash to keep the entry fee relatively the same. Number of players is in the low 100's. I've been to a couple of these and they are fantastic. Nick takes it seriously, so there is security checking bags with wristbands like at Eternal Weekend. There are also giveaways and special prizes. It one of the special player run events in a format that mostly exists because of such player run events.
Take all this with a grain of salt as I'm sure if the details were fixed, Nick would let us know. But if you are interested in attending a Paper Vintage event and have means to do so, I would definitely recommend this one.
