Not only was it the first photograph ever taken in Barcelona, but in the entire Iberian peninsula as well. The image was taken on November 10, 1839, from a terrace on Pla de Palau, in a public act. The photograph was then raffled to raise funds, and this is when it became lost. It is unknown whether it still exists and who may possess it 175 years later.
If it was lost how can you show it?
