My Mad Men party fits the "vintage" category best (the murder mystery parties and Halloween parties don't have vintage flair but if anyone wants I'm happy to share my decoration ideas).   We had a Mad Men party last summer - we invited our friends who are all fans of the show.  Here are some pics of what I did for the party (sorry in advance there are alot haha):

Vintage magazines out on the table:

My friend Katy with our hedgehog cheese ball.

Hubs checking out a Playboy from the 1960's (I can't remember the exact year).

More vintage books and magazines.

A rotary phone.

Deviled eggs of course!

That is a plaid tablecloth from my Grandmother - 

I had to share this pic of my friend Lynda - she looks straight out of the early 60's.

Vintage looking bottles of soda

And lastly hubs and I with our fake cigs and Old Fashioned.
