Screen Stars is the theme of this year’s 10th annual Auburn Heights Invitational set for Sept. 18 at Auburn Heights in Yorklyn. Classic cars matching those that appeared in films such as The Graduate, American Graffiti, Animal House and Magnum P.I. will be on hand as well as some of the finest early automobiles of the last century. Visitors can also explore the recently renovated Marshall Steam Museum, which includes a new attraction: an exhibit of 80 extraordinary pedal cars. Event admission includes entry to the Marshall Steam Museum, which houses the world’s largest operating collection of Stanley steam cars, plus free steam-popped popcorn from the museum’s restored 1930s Cretors popper, and rides on the Auburn Valley Railroad. A silent auction and raffle featuring unique and extraordinary local items round out the day’s activities. All proceeds from the event support the Marshall Steam Museum and Friends of Auburn Heights. Tickets are $20 in advance, $25 at the gate with discounts for those under 15. Visit AuburnHeights.org
