Lovely Vintage Studio Pottery Weed Vase in Mottled Blue-Purple Glaze

I know more of you look to me for folk art and curious things than for pottery, but I'm a great lover of functional studio pottery vessels, and a firm believer in the power of a lovely pot, with weed/bud vases my favorite of all forms. And what a pretty and serene one this is, almost perfectly round, feeling like a gulp of sky.  In excellent condition, a sort of soft blue-purple, with some mottling to the glaze and a bit of variation on one side. Lovely.

Approx 4" t x 4" diameter and in great condition, no issues. Initialed in graphite on the underside.
