Charging Donkey, Early 20th Century Hand-drawn Pen and Ink Postcard

Tis the season for the hard-charging donkey as I post this, which I believe is what this creature is! And indeed, I love how determined--possessed, really--this airborne donkey looks! The message on the back of the postcard, written 100+ years ago by the RWM who made the drawing in black ink, is pretty great too: "After going to the zoo and have a large supper. This is what you might expect."

3 1/2" x 5 1/2" inches and in good condition. A little staining here and there, which I think just add to the ambiance!
