I believe this to be the basin portion of a pair of wallpockets called Lavabos but I purchased it as a stand alone “Wall Planter”

If you’re interested go to my listing on eBay to see the description.  It is a lovely turquoise blue with brown flecks and if my outside walls were not made of plaster, I’d hang it on my patio as a bird feeder.  Please note that the first picture does not do the color justice  ~~dru~~
