The best way is to log on to the Javits centers website.
search for the calendar & see which shows are coming up.
Yuo want to do the:
ENK children
The childrens show
Moda
etc..
you will not be able to show up there without a business ID so you first want to choose a name & register your business legally-it;s worth it and it does not cost a lot.
My accountant does it for his clients.
from there..the sky is the limit.
Good luck!
