POLLOCK Pottery Handled Vase - Arts & Crafts?

I have a pottery vase with a slightly abstract design, but the shape reminds me of the arts and crafts era. This piece is 8 1/4" high and measures 2 3/4" diameter at the top, flares out to 4 1/2" near the base and then ends up at 4" across at the bottom.
It has two handles, a carved abstract design and is in a rust colored glaze. The interior is also glazed. The pottery body appears to be a yellow clay and it is hand signed on the bottom with the name POLLOCK and stamped with the numbers 113. Because of the number stamp, I wasn't sure if it would be considered studio pottery. I purchased this at an auction in Seattle, Washington many years ago but there was no information available at the time and thus far I have been unsuccessful in locating any information about the potter, pottery or when and where it was made. As always, thank you in advance for any help.
