Food to Die For is a wonderful book - mostly of foods which were popular for funerals in the past. I own this book and it's very good! If you're interested in period recipes or just social history - it's a must have.
This book is published by the Old Lynchburg (VA) Cemetery. This is a wonderful place to visit and you can get lost in it for literally hours! They also sell beautiful period roses and other heritage plants - they have a great gift-shop with lots of mourning related items for sale.
Here is their website - it's a really good one!

Also - don't miss the Surratt House mourning exhibit if you happen to be up that way!
