vintage Rock Sharpe Libbey etched glass stemware tall water goblets wine glasses 3007-12

Set of eight 7 7/8" tall Rock Sharpe water glasses pattern 3007-12. I don't know the 'real' name for this cut or etch, sorry! One glass has a makers flaw to the rim, but aside from that, this set looks excellent - crystal clear, showing no signs of wear.
