This summer, research was conducted for a history of Woodside, Queens, published in Volume 38 of New York Irish History.
Parts of the article focused on the section of Woodside bordering Jackson Heights, Elmhurst, and Maspeth, once a separate locale called Winfield.
During research, a New York Times article from April 30, 1928, was discovered, stating:
TROTSKY LANDMARK IN QUEENS TO PASS; Hall in Winfield, Where Legend Says He Planned Soviet Revolt, to Be Razed.
The landmark was located at 71st Street between 41st and Woodside Avenues.
