Big pottery flower frog vase, retro mod bulb shape, cobalt blue color

Big mod pottery flower holder vase... this is unmarked, but is made in Spain, we think? (It came to us with a collection of Spanish and Italian art pottery, does not look like a made in Italy piece to us.)

The vase stands about 9 1/2" tall, with large holes to easily hold flowers with heavy stems, even sunflowers! It's in excellent condition.
