My relatives in Spain have run a hardware store since 1870 - that's three generations. They have a web site that contains a history section, with these old photos. I did my best to translate the Spanish.
1915 - hardware store and bar.
The little boy all the way to the left is my grandfather, age 4. He had 4 brothers and two sisters.
1936 - the business was hard hit by the Spanish Civil War, with supplies being requisitioned and sent to the front.
