Authentic British Style Imperial Pint Glass with Etched Seal

Is this a SET of glasses or just ONE? thanks.

What style of glass is this? Tulip (think ubiquitous Guiness glass) or English nonic? The pictures show both.

Question for recent buyers: Where are these made and are they properly etched? Looks like many of the answers and reviews are for an older product

Made in England, yes or no?
