Picos de Europa mystery

Here is an interesting period shot of Spanish hunters and their quarry hanging in the bar opposite my holiday home in the Picos de Europa. I assume it was taken at the end of the 1920s or early 1930s. 

 

The car looks to be a Hispano-Suiza Alfonso or similar. Can anyone confirm?  

 

The good news is the hapless bears have returned to the area and on occasion cross though our garden there, as do the wild pigs.
