Hand blown, cobalt blue glass, not particularly well made either. Could be anything from an amateur taking weekend or college classes, to an artisan who sells at a craft show. Not much value and not terribly old.
Is there a tag on it with an Artist's name or Initials or anything etched into the bottom like initials or a name? If not it is just a random blue glass pitcher worth what you paid for it, but you could always try and mark it up and see what people will pay for it.
