I think this little cocktail book is really cool. You can make 12 cocktails from the 1950's that were served in the UK. These beautiful heart mats were made in Great Britain. You can have a retro party and offer the 12 cocktails and uses these as your mats. The little book was included with the purchase of the mats in the Mid-Century. Made by Hostess. There are 35 heart shaped mats in New (old stock) condition. Each mat measures 3 inches long and 3 inches wide.
