There were some spanish bike manufacturers after the spanish civil war, now they are all gone. A while ago I managed to buy a full family album. It was advertised as "old photographs, many of "brand" bikes. I'm a collector of that brand and had to buy it. At euro 100 I was the only bidder, but I knew I shouldn't let it go. For the pictures I saw I knew it was the family album of some Alfredo Isanda, the only distributor of the Marque in Mallorca back in the fifties. Along with family pictures, there were pictures of the grand opening of his dealership, races, and so on. Even an autographed picture of Umberto Massetti. When I asked the seller where did he get it he told me "on a lot I bought". No doubt the man died and the family got rid of everything that wasn't valuable -if they only knew somebody would pay eur.100 for the pictures....-
I still believe the man died without offspring or they were in a bad relationship. Otherwise I cannot understand why somebody would get rid of his dad's pictures, if only to pass them on to the grandchildren...
