Blenko? 22" Tall Cobalt Blue Footed Long Cylinder Vase - 1960s?

Possibly Blenko Glass. In a Blenko group on FB, a woman showed me hers that was almost an exact match to mine. This piece, in the rich cobalt blue color, is stunning. It is a dark rich blue that comes to life when the light hits it. Not only is it very tall, but it is wide and thick at the base and it is very sturdy on the ground. I cannot call it a swung vase, but it is the height of one but has a rounded off flat mouth. It doesn't have any cracks or chips, and no scratches. the vase is in pristine condition. It is a gorgeous home decor piece to add to your glass collection.
