Here's a number of before and after photos for Puerto Vallarta and surroundings.
It's always fun, interesting, nostalgic to see towns from before they grew up, before they became known, and just wonder at how things change, and sometimes don't change.
Most photos are from the 1950s and 1960s, around the time the local photo studios established themselves in the town.
