Vintage postcard of the Tweetsie Railroad, an amusement park in Blowing Rock, North Carolina that is no longer in operation. The card is postmarked Blowing Rock, NC 1971. Please see photos. I pack postcards in a clear postcard sleeve and then a clear rigid top-loader and ship with eBay standard envelope I offer combined shipping discounts and will refund the extra shipping paid on multiple orders. The shipping discount varies according to the size and weight of items, but small, lightweight items can often be added to an order for little or no additional shipping fees.
