For Your Health to Czechoslovak Spas

Charming post WW2 poster for Czechoslovakian Spas. The butterfly wings feature stamps including the British George V Victory 3D (3 pence) as well as stamps for India, Sweden, Norway, Denmark, Netheralands, Russia and other allied countries. The British Victory stamps were issued in 1946.
Printed in Czechoslovakia. Cervený Kostelec.
In good condition, some wear on edges. Would linen-back perfectly.
