Invoke ©2017 Galen Valle. All rights reserved. Invoke – Conceptual portrait art. Created using a fantastic model photo from Alice Spiegel . The vase has made a couple of appearances in my artwork recently. It lives in a corner of my house and (although it is quite large), I tend not to notice it for months/years due to its odd shape and very dark color. It creates kind of a void and hides in plain sight. When I do notice it, I remember how much I like it and I sometimes expect a genie to come out of it.
