Last year the local dodge dealer parts desk had a stack of Mopar calendars they were giving out for free.

One was a classic muscle car version, and the other was an off road/truck/jeep version. they were pretty nice.

I'm going to try to swing by and see if they have them again this year.

EDIT--yes it's the same calendar they are selling on Ebay for $12 or $24 bucks...
