Blue-tint Glass Vase

This is a mid-century blue-tint glass vase in a square shape. The color is not a solid blue but a blue-tinted clear that actually turns to a purplish color tint in sunlight. There are some small bubbles and stretch-like marks in the glass. It is thin glass at the top and tapers down into a thicker base. It has a 1 1/2" by 1 1/2" mouth opening and is 6 1/2" tall. - Unknown maker
