Cedar Mesa Wolf Vase, Vintage Native American Southwest Folk Art Pottery

Beautiful vintage Native American hand painted pottery vase (approximately 8.50" tall, 8.75 wide, 4.50" mouth diameter) decorated in greens and grays with wolves, trees, teepees and symbols signed by Eva. There are some white marks on the rim of the vase, I am not sure if this is how it was manufactured. Please review all pictures prior to purchasing.
