THE 150th anniversary of Charles Rennie Mackintosh’s birth will be celebrated with an exhibition of unseen works.

Glasgow Museums will commemorate the landmark of the Glasgow-born architect and designer with a programme of events in 2018.

One of the highlights will be a temporary exhibition at Kelvingrove Art Gallery and Museum of works by Mackintosh and his contemporaries. The group – Mackintosh, his future wife Margaret Macdonald, her younger sister Frances Macdonald and her future husband James Herbert McNair – became known as "The Four" in the early 1900s.

Many of the works will be on display for the first time in a generation, while others have never been shown in public before.

Alison Brown, curator with Glasgow Museums, said: “Charles Rennie Mackintosh is rightly celebrated around the world as one of the most creative figures of the 20th century.

“He is regarded as the father of Glasgow Style, arguably Britain’s most important contribution to the international Art Nouveau movement. As we approach this significant anniversary I am thrilled Glasgow Museums will join in a city-wide celebration with an exhibition commemorating one of their most famous sons.”

A Museums Galleries Scotland grant enabled museum chiefs to recruit an assistant curator to develop the exhibition in tandem with a wider Charles Rennie Mackintosh programme.

Glasgow Style designs were created by teachers, students and graduates of Glasgow School of Art between about 1890 and 1920.
