Painting on top of photocopies using Karo syrup and watercolors.

This is a photocopy of my dad, 1950, in front of the mission in Monterey, CA.  I have been playing around using Karo syrup with my watercolors.  The syrup allows the colors to drift more slowly into one another creating a vintage postcard effect.  I lay the photocopies out on parchment paper to paint and cure.  Once cured (about a day) I varnish them with an acrylic varnish - the look remains the same, but not sticky.
