San José de Valderas photographs
On 1 June 1967 photographs of a disc bearing the Ummo symbol were taken over San José de Valderas (Alcorcón) and sent anonymously to the press.
1967 CE · 40.35, -3.82 · status: hoax
The account
The pictures became the most reproduced images of the Ummo affair. A metal tube with plastic sheets supposedly left by the craft was also 'found' near Santa Mónica.
The sceptical view
Photographic analyses, including by French researchers, showed a small model hung on a thread close to the camera.
