American brewers were much quicker than their counterparts in this country to realise the marketing potential of Special Brews for holidays and similar occasions. Not just in the bottle either; this label is for a half barrel, that is 15½ gallons, of Piel’s Special Holiday Beer. That would be about 12½ gallons in the UK. Imperial measures in America are just about the only thing they do which is smaller than ours. I believe this label to have been issued just after the end of prohibition, in 1933 – 1935.
