"1000 Stone Ginger Beers by Ross & Christine Roycroft, 1983, 100pp (ISBN: to be added)
A pictorial price and rarity guide featuring Australian stone ginger beers and demijohns. Absolutely essential for all Aussie bottle collectors. This book originally cost about $15 to buy, but now sells on eBay for up to $100!
Copies are usually available from bottle shows for the very reasonable sum of about $17 from the Roycrofts (authors)."
Not many 32 oz gingers around, pretty much the only one I can think of is a Harrisons, Fitzroy and I've only seen one or two of them, there are quite a few 26 ounce gingers though. What brand did you have in mind?
Phila, that is a really good book, the prices are a bit dated now but it's nice to have so many photo's of ginger beers in one book.
Really not sure how much the 32 oz Harrisons would be worth, the 26 oz one is worth around the $50 mark but the 32 would have to be a fair bit more I'd think.
