First Edition. Original soft suede printed 'wrappers', 121 pages, 7 by 5 inches. This copy nicely inscribed and signed by Iverson at title page. Attractive post-prohibition cocktail guide, including recipes for such drinks as: American Flag, Waldorf Fizz, Paree Cocktail, Blinker, etc. An article in a contemporary Santa Cruz newspaper muses about this title thusly: "Cocktail hour visitors to the restful St. George hotel tap room are talking about John R. Iverson, recently 'discovered' by them as not only a modest, sincere and friendly bartender, but as an author of merit and one of the country's outstanding authorities on drinks and how to make them. Hiddin for almost the entire two months he has been at the St. George, his prominence under a natural screen of self-effacement, the young but serious-browed Mr. Iverson stood today revealed as the author of a deluxe 'cocktail manual, "Liquid Gems." A highly different but thoroughly authoritative book of drink recipes accepted as "tops" in its line by leaders of the beverage industry. Mr. Iverson, formerly of the world-famed Savoy hotel, London, compiled and published his novel work while at the California Golf Club in San Francisco. Beautifully printed and bound". Scarce, WorldCat locates two copies, both at the University of California. Very Good, covers darkened with modest wear.
