Boston T Line Subway scroll - Letting it dry

Here is a photo of a custom train scroll with destinations of the Boston T Line that I am making for a client.  I took this photo after spraying the canvas with a water-based acrylic coating to protect it from scuffs and scratches.  The gloss will dissipate when the acrylic  dries up.   I will wait until tomorrow for the protective coating to cure before I stretch the scroll on 1 1/2 inch thick gallery wrap stretcher bars.

The Canvas size is 24″ x 64″.  The final size of the scroll after stretching it on gallery wrap bars will be 20″ x 60″.
