Bass prince of wales 1929

I have been given a bottle of beer which i think is commemorative, it looks like a two pint bottle dark with Prince of wales 1929 stamped on it its still corked and has about 1/4 of the liquid left in it.

does any body know anything about this.

Maybe these links will help you out.  I don't think it's a recent beer.  It was probably brewed on July 23rd, 1929.  It was given out to employees as gifts.  I appears that quite a few of them are still around.  They have been auctioned off quite a few times in the past decade.  There is even a couple of tasting notes in Beer Advocate.  I believe that they were bottled in early 1930.
