Did I see Machida Kumi in Vienna?

Last week as I was entering Vienna's Stadtpark, I found this grafitti on an electrical register behind some bushes.

Immediately I thought (I had no choice!) of Machida Kumi, an outstanding Japanese artist whose line I admire completely delighted. If you don't know her, it's worth a look at her work (still one more week of the exhibition in Hannover, but I'll miss it...).
