Scottsdale, Arizona. Each year in January, Barrett-Jackson holds a classic car auction. The automobiles offered for sale at this auction are often a labor of love. Many hours of careful attention to detail create the magnificent works of automotive art. This week’s photo challenge is “Careful”. You can read the entire challenge post here. I am later than usual in submitting my collection of photos as I am travelling, gathering more images to share with my readers. Please excuse the brevity of my submission. So, better late than never, here is my selection of carefully prepared images for your review. Click on an image to enlarge it and to scroll through the gallery.
