I've seen a couple posts claiming to show Iran in the 1970's.
Are the pictures people post just the wealthy? What was the average person's life like? What was their job and level of education? What did they do in their freetime?
There's a great new book on this

In the 1970s Iranians were about 50% literate, urbanization rates were quite low, and average lifespans were 55 years
The UN's Human Development Index for Iran shows that it was low and not at all rising before the revolution,

and after the revolution living standards significantly improved as Iranians doubled literacy rates, added 22 years to average lifespans

According to the UN,
Only one other country (S Korea) was able to do better http://www.ir.undp.org/content/iran/en/home/countryinfo.html
The UNDP made a chart showing Iran's progress in living standards compared to the rest of the world - Iran is the green line
