On first glance, this doodle of a menorah may seem of little significance but its creator was none other than Pablo Picasso.

In early 1958, he received a letter written on behalf of Wizo and he drew the menorah on the envelope to show his intention to help the organisation, according to Linda Morris, curator at Tate Liverpool - whose new exhibition, Picasso: Peace and Freedom, opens next month.

The artist gave not only money to Wizo but a painting to be sold at its Cannes conference in 1964.

His papers include a certificate sent in gratitude by Wizo and signed by its president, Rebecca Sieff.
