Size 18x24 inch, 1,5 inch thick canvas - gallery profile that does not require framing, but can be framed if you wish to do so.
This painting is varnished.
Rady to hang with a wire at the back.
Hang it on your wall. Enjoy. No care necessary.
Ok, if it gets dusty you can wipe it down (damp cloth or duster) every now and then. Usually just the top ledge.
