Oh how I love vintage Christmas books. Especially when it's in Japan. Not that I speak the language, I just adore how Japanese illustrate and design their stuff. I don't know how they do that but everything they design and illustrate always come out beautiful.
I have been a children book illustrator for 5 years and I am far beyond the Japanese's level in illustrating. Sigh.
Just see for yourself and enjoy.
You can find and buy these book here.
