The DDC's key membership barrier is physical space. [fact]
The New York DDC currently has 2,000 members; in most years there is a waiting list for admission. Although requirements for membership are strict, the main constraint on membership is space, not the inability of dealers to meet the membership requirements.
QUESTION: What prompts a waiting list despite strict requirements — what is the selection process and how crowded is the gallery space?
