Perfect-sized Planter / Flower Pot!

i've had several pieces like this which seem to be made by the same company or person. they are fairly thick, but beautifully made w/ gorgeous glazes on a yellow, gravelly base [not sure the correct term for this]. i have no idea how old they are, but i really like planting in these pots. would love more info, but without any sort of a signature, i might never get it.
