A super set of six retro drinks coasters. Likely vintage 1980s, these are by GWS (Oy G. W. Sohlberg Ab.) and are made in Finland. Each mat depicts a different mixed cocktail, to the reverse is its name and recipe with (old school) measures. We have Dry Martini, Bacardi, Whisky Sour, Manhattan, Tom Collins and White Lady. The coasters are flat and round with a small lip. Black with retro prints. 
Each one is 8cm x 6mm high - quite petite and perfect for a mid century/retro home bar. Flat inners are about 7.3cm wide (please check they suit your glasses). Great condition coasters with no signs of use, just minimal wear to the bases. 
Price includes P&P to the UK.
