Expo 2020
Here are some of the envelopes I submitted for the exhibition Mail Art 2020 in Strasbourg. Among them are also some that were not exhibited.

Expo 2019
You can revisit the exhibition "Paintings and Sculptures" in the "Galerie op der Kap" (Paintings Fernand Bertemes, Marc Bertemes and Patrick Sadler, Sculptures Gérard Claude) by consulting the albums below in which you will find photos and documents, which will allow you to relive it.

Expo 2016
"Water Lilies"
A pond reflecting the sky and transparently showing its water world. Like a carpet of flowers that has been built in conjunction with various physical elements (the earth where the roots are anchored, the water they grow through to finally float on its surface and bloom in the air due to the photosynthesis, which is powered by the fire of the sun).

Expo 2013
"Exhibition 2013"
"When a Model meets a Painter" is an exhibition from Patrick Sadler on the theme of the female body at the "Maggy Stein" gallery in collaboration with Monica Gomes, Christian Mille and Lucienne Deviscour in Bettembourg.

Expo 2011
"Ehibition 2011"
The exhibition, organized by the A.s.b.l. "Frënn vun de Caper Piwitschen" under the High Patronage of the Municipality of Mamer took place from 25 November to 17 December 2011 at the "Galerie op der Kap", 70, route d'Arlon in Capellen (opposite the church).
Three friends, Fernand Bertemes, Pétra Werlé et Patrick Sadler, painters and sculptors, met to expose together their works.
The profits from the sale were entirely dedicated to generous charitable projects.

Expo 2009
"Exposition 2009"
"Figuration Non-Figuration"
The figuration/non-figuration project proposes to compare in a single exhibition the two worlds of painting to allow to observe the elements which oppose them and those which connect them.
It allows us to observe the passages from one world to another and questions our knowledge of the notion of figure and non-figure, of representation and visual abstraction through the pictorial medium.
Instead of separating figuration from non-figuration, the "no" of non-figuration does not constitute a negation but rather an encompassing of figuration, and vice versa.
The idea is to offer an inter-, even transdisciplinary exhibition, where a painting can be both figurative and non-figurative.
To conclude, this project brings together plastic research on the appearance of phenomena and encourages the questioning of acquired definitions.
During the opening of the exhibition, there was an experimental and intuitive musical intervention by Giuliano Arpetti, who interpreted under the visual influence of the paintings a sound improvisation of the figuration/non-figuration.
