Seeking El Salvador Maps & Photos 1970s/80s

I am doing a project on the country of El Salvador in the early 1980s, and I am having trouble finding some of the images/sources I need. It is easy to find infographics and images relating to the ongoing civil war, but that is not the subject.

What I need are atlas, tourist guide or roadmap style visual references to El Salvador: places, businesses, thoroughfares and so forth. Basically the sort of thing someone in 1981 would want if they were navigating their way around El Salvador. I am also searching for images of everyday life, clothing, architecture, building layouts, etc. for a look into how El Salvador actually looked to people at the time.

The city of San Salvador is of particular interest, but really anything normal/business/residential/peasant could be useful to me.
