Rare PARO stationery #15 “Kohvik Kultas”, Tartu-Pärnu 1938

Rarest stationery from PARO issue. Less than 10 are known to exist in used form (some think only about 5-6 exist).

Includes original letter from someone working in tuberculosis hospital. Real item, not a philatelic production like most of used PARO series.

Back side has advertising for lamps which reads: Russian lamps. A lot of light for little money!

Note that condition is not very good, has some stains and coloring, especially on back side.
