Not the kind that protects your beloved machine from dust, the postal kind …

The LUBRAPEX — Luso-Brazilian Philately Exhibition — is a stamp exhibition in which only postal operators and collectors from Brazil and Portugal participate. Since 1992, Portuguese speaking countries and territories have also been taking part.

It is the oldest Bilateral Philatelic Exhibition in the world, having been conceived by Brazilian diplomat and philatelist João Paulo do Rio Branco, in order to promote the strengthening of friendly relations between postal operators and collectors from the countries involved.

Held for the first time in 1966, at the National Museum of Fine Arts in Rio de Janeiro, this event celebrated its 50th anniversary in 2016.

The five authors featured on the stamps and the cover above, form the basis for contemporary Dutch literature (2013):

Simon Carmiggelt (7 October 1913 – 30 November 1987) was a writer, newspaper columnist, and television personality.

Gerrit Kouwenaar (9 August 1923 – 4 September 2014) was a journalist, translator, poet and prose writer.

Louis Marie-Anne Couperus (10 June 1863 – 16 July 1923) was a novelist and poet.

Adriaan Roland Holst (23 May 1888 – 5 August 1976) was nicknamed the “Prince of Dutch Poets”.

Godfried Jan Arnold Bomans (2 March 1913 – 22 December 1971) was a popular author and television personality.

Max Rudolf Frisch (May 15, 1911 – April 4, 1991) was a Swiss playwright and novelist. But why commemorate the centenary of his birth with what looks like a late-model plastic (Japanese?) “Adler” portable typewriter?

Like Tennessee Williams, Frisch used a variety of typewriters and had a soft spot for the Olivetti Studio 44. A Frisch-related typewriter link can be found at: typewriters.ch.
