Thanks, Allison. Yeah, i think its probably limestone (my using of "sheet rock" is likely incorrect
). It has the look of plaster from the acrylic gesso sealer.
What will be an interesting challenge is curing enough layers of oil on top of the work to withstand the elements--i've had poor result with various polyurethanes in exposed sunlight.
Billmahler, Dcam, Phranque and Carol, Thank ya'll for the encouraging and kind words!
