There are tons of lectures and presentations throughout the year in Greenwich. One neat series that I found are the Evening Lectures: Under the Big Top at the Bruce Museum. Tonight is the final night of this three part series. I apologize for not giving you much notice. Better late than never, right?
"Nov. 18. The Photography of Frederick W. Glasier and the Ringling Circus by Peter Kayafas, Director of Eakins Press Foundation and co-curator of HEYDAY: The Photographs of Frederick W. Glasier at the John and Mable Ringling Museum of Art, Sarasota, Florida." $10 for non-members and $8 for members.
If you have an interest I would recommend contacting the museum (203.869.0376) as space is limited.
