Click on the thumbnail to see the entire image. This is my all-time favorite Halloween comic from Greystone Inn. It is an homage to Philadelphia’s Henri David Ball — a fantastic costume party thrown every year by jeweler Henri David. Tickets are $25 for costumed revelers and $60 for voyeurs. The proceeds go to charity. This year’s fete is at the Sheraton Center City Hotel at 16th and Race Streets in Philadelphia. Advanced tickets are for sale from the Halloween Jewelry Store, 1329 Pine St.: 215-732-7711. Get there prior to 10 p.m. if you’re buying tickets at the door, because the lines get long.
