All of these were painted using gouache on illustration board, by the way, as this is still my preferred medium even in this age of digitally created art. Frankly, I wouldn't even know how to achieve the same results using Photoshop and, unless one uses a Cintiq, I wouldn't even have the type of control necessary to do it digitally. Besides, I just happen to prefer the look of real paint on board, aesthetically!
Finally, here is the logo featuring Mickey and Minnie that appeared on the back of each of the three illustrated cards. I've enlarged it considerably from its printed dimensions of approximately 1 1/2" in diameter, so it's a bit blurry as a result.
This will likely be my last post before the 25th, so a Merry Christmas to all of my blog readers!
