Here is a rare Spanish interview with Walt released in the August 5, 1965 issue of La Actualidad Española.

Two highlights:

"Walt: Of course, I am not Spanish. I was born in Chicago. But I love Spain and the Spanish people." [And yet the canard about Walt being born in Mojacar, Spain lives on to this day!]

"And Walt tells us about his latest trip to our country: 'I was on the Costa Brava, in Barcelona, in Madrid, and in Algeciras. From there I took the boat to New York. I arrived in Port Lligat without warning to make a surprise to my great friend Salvador Dalí. You know how it is: if someone is warned about your visit they have to worry about all the things to prepare, so I did not warn him.
"Gala, Dalí's wife, was fishing in a rowing boat. The house was empty and I finally found Dalí among the rocks, spread out under the sun, with his huge whiskers all wet, points down."
