In the first two decades of the 1900s, Raphael Tuck & Sons, England’s foremost postcard producer, published a series of Postcard Painting Books, an introduction to mail art for children.
In addition to colored pictures, for reference, and outlines to be painted in, each book included a set of watercolor paints.
After painting, the postcards could be removed, addressed and posted, as was the card below, circa 1910.
Today, the individual cards and books can be found on eBay and at Abebooks.com.
