Artwork painted by a woman killed in the London bombings in July last year will be shown publicly for the first time later this month.

Miriam Hyman, a picture researcher of Holyoake Walk, Hampstead Garden Suburb, died last July 7 after boarding a number 30 bus which exploded in Tavistock Square.

Known to her family and friends as Mim, Ms Hyman, 32, studied French and art history at University College London. The exhibition, entitled Mimento is to be held at City Hall, the seat of the Greater London Authority, next to Tower Bridge.

Mavis, Miriam's mother, said: "It always gave Miriam pleasure to give pleasure to others. One of the ways she did this was through her painting and craftwork and our hope is that this exhibition will bring a smile to many people's faces.

"We would also like to raise awareness of the Miriam Hyman Memorial Fund, so that her life may continue to have value, particularly for those who have problems with eyesight in developing countries."

The fund was launched in November last year and is working with the charity Orbis UK to improve the sight-saving skills of eye-care specialists in the developing world.

To coincide with the exhibition, a book containing more than 90 of her artworks entitled Mimento: the Paintings and Pastels of Miriam Hyman, is being published by the family.

Mayor of London Ken Livingstone said: "Miriam's vibrant and life-affirming paintings are testimony to her undoubted talent and much spoken of generous spirit and it is fitting that they should be displayed in City Hall.

"Miriam's family have been determined that a positive legacy should grow from Miriam's tragic and untimely death in the London bombings."

The free exhibition will be open between June 19 and July 12, from 8am until 8pm, Monday to Friday.
