The Label
A paper label identifies 'J. Juan Pastor — Artesanía Selecta' at Provenza 66, Barcelona, with handwritten entries 'N.º 325' and 'Julio 1968.'
J. Juan Pastor / Artesanía Selecta - Spanish Chess Clock, Barcelona 1968
What the Number Means
The number could be a serial, order, invoice, or inventory reference. It should not be treated as proof that 325 chess clocks had been produced.
A Workshop Attribution
The label strongly suggests a small artisan or workshop source rather than a casual owner's inscription. The safest public name is J. Juan Pastor / Artesanía Selecta chess clock, Barcelona, July 1968.
The Joaquín Juan Pastor Question
A Spanish publisher named Joaquín Juan Pastor used a similar imprint, but his documented publishing activity ended before the clock's date and no evidence connects him to the Provenza address, Artesanía Selecta, or chess equipment.
Historical Significance
The clock is unusually valuable because date and workshop-style identity survive together. At the same time, it demonstrates the discipline required in object research: a plausible name match is not the same as a proven maker biography.
