When it’s cold and/or rainy outside, or you’re just plain bored, a jigsaw puzzle is a great alternative to watching TV or playing video games. To satisfy your inner gearhead, Serious Puzzles offers an extensive lineup of automotive-themed tests of determination and patience. Included in the mix is a 1,000-piece license-plate puzzle that includes both current and older tags representing all 50 U.S. states. Serious Puzzles also carries a variety of classic-vehicle and city-themed puzzles, many of which were previously been created as poster art. Prices range from $10-$21, depending on the subject matter and whether the puzzle is of the 300-, 500- or 1,000-pieces variety. Check out the selection at www.seriouspuzzles.com/sjigscarstrucks.asp.
