1929 Postal Union Congress Stationery

10^th May 1929 PUC low values with a Postal Union Congress, London CDS postmark on the official Congress stationery. These stationery first days are hard to find. A rare opportunity to acquire one in good condition.

The ninth Postal Union Congress opened in London on the 10^th May 1929, with the new stamps issued on the same day. Despite some mixed initial reaction to a new set of commemorative stamps, (King George V was known to not be a fan of more commemorative issues), general sales were very successful and the set has become a classic.
