I started developing an eye for such sightings: today while eating a shawarma in the touristic city zone, something drew my attention: an add at the next-door shawarma place, they were offering a free lemonade for some orders. No, not the lemonade was of interest, but a drawing on the banner. A quick check on my clipart collection confirmed: yet another use of my freely licensed clipart images. Is not a spectacular image, made in the early days when I was learning vector graphics and Inkscape (still called Sodipodi), but it was of use for someone.
PS: that's not that unexpected, is at the top of the first page in the Google image search for "lemonade"
