This is acrylic on heavy floor canvas with non-slip backing sides folded under and sealed no rough edges . Works best on hard surfaces not rugs so well. This is one of my favorite ones. This is art you can walk on. This has been sealed needs several coats of poly-finish for protection. A real show piece floor art or if you choose hang it most people do.Size is rough I just cut prime iron under the sides measure my eye.Pins removed after photo.
