Here are some fun ideas that I hope you can use (or at least can be a catalyst for some of your own

* Have small namecards printed on cream cardstock and placed around the table in the Godfather themed font (there are some great free fonts out there - try Simply the Best Fonts for a good start.)

* Peacock feathers and colors were also very popular at the time

* If your guests are more on the creative side (me and my friends are all actors and artists as well ) consider inviting a couple of 'unexpected guests' to the evening to make it special.  Have someone you know (preferably someone your hubby doesn't know) come in to treat him like a gangster (i.e. a gin runner in costume coming in to confirm a 'shipment' across the Canadian border, a police inspector or Elliot Ness warning him that he WILL be caught if he continues his 'business' in your city, etc.)  I've personally done these types of things MANY times for different birthdays and special occasions and believe me, the birthday boy will have something very fund and creative to remember!

* Fringe on women's dresses were popular - visit your local fabric store and pick up a couple yards of fringe to cut in pieces and wrap around the glasses, etc.
