No, not really. I just tried to make it look like that.
Carved from pine project board. I held it down in the center with masking tape/super glue, allowing the edges to rise during carving to create the eaten-away-at-the-edges look. Sealed with shellac. Sculpt Nouveau copper B, light green patina, and Age-It complete the fakery.
Should I frame it, or leave it mounted as-is?
