Postcard Delight: part 4

This week's post card is very different from the previous ones: no framed photographs this time, but pure illustration. No idea when this one was made though — the Leonard A. Lauder collection book I previously mentioned doesn't contain any similar designs.

The person featured is 大石内藏之助藤原良雄 (as written on the card). That's Ōishi Yoshio, also known as Ōishi Kuranosuke. Wikipedia has more info (JP).
