Lady with Parasol by Katie Cook

I think it was at Boston Comicon a few years back... maybe 2012 or so... Katie Cook was there and she had a plethora of these teensy tiny (3" x 4") ink and watercolor paintings she was doing and selling at her booth. They were all awesome, and of course the superhero ones sold like hot cakes, but looking at the ones I picked it appears I was in the market for animals and umbrellas. Interesting. If this happens to be a character from something I don't know who she is, so I just call her "Lady with Parasol." If you know who this is, please let me know.
