Roberto's envelopes always seem to have multiple "goodies" included with them. And his envelope's are not the least of his treasures!...
Envelope back: Toros en Sevilla 2011 (gorgeous!)
...And best of all, this piece of artwork inside: an asemics collage entitled "Asemics Aerial Map." usually my photographs admittedly blow chunks, but somehow the light was just right for this photo, and you can see the subtle variations of color swaths in both the primary colors. It immediately brings to mind the confluence of two rivers, the asemics serving as the unending, mesmerizing waves that a person could be hypnotized by forever sitting on the riverbank and watching the water go by. Thank you, Roberto for your kind words, and sharing this great artwork with me!
