Number of tickets to win Tête de Femme will be capped at 120,000 and proceeds will go to Alzheimer’s research

A raffle in France is offering the chance to win a portrait by Pablo Picasso for the price of a €100 (£87) ticket, with proceeds going to Alzheimer’s research.

Picasso painted the gouache-on-paper Tête de Femme (Head of a Woman) in 1941. The raffle organisers’ online sales platform says the number of tickets will be capped at 120,000, meaning the draw could net €12m if they are all sold.

From the proceeds, €1m will be paid to the Opera Gallery, an international art dealership that owns the painting. The raffle will benefit the Alzheimer’s Research Foundation, based in one of Paris’s leading public hospitals.

Organisers say two previous Picasso raffles raised more than €10m for cultural work in Lebanon and water and hygiene programmes in Africa.
