KNOXVILLE, Iowa -- Thanks to the hard working staffs at Pella Printing in nearby Pella and Mail Services in Urbandale, the National Sprint Car Museum’s annual holiday mass mailing packages were sent out today from Des Moines. Sprint car fans around the country and around the world are urged to check their mailboxes within the next seven days for the once-a-year offers from the non-profit museum foundation. If any sprint car fan hasn’t received the pre-Christmas museum membership flyer and museum store brochure in the mail by November 26 and would like one, the person is urged to contact the museum toll-free at 1-800-874-4488 or via e-mail at giftshop@sprintcarhof.com and another package will be mailed out that day. The National Sprint Car Hall of Fame & Museum is open seven days a week, year-round, in Knoxville, Iowa. It is closed just four days a year: New Year’s Day, Easter Sunday, Thanksgiving Day and Christmas Day. The on-line museum store is accessible 24 hours a day, seven days a week, at www.sprintcarstuff.com.
