The tile work is in the 1940's to 1960's era. The colors (aqua, yellow, olive…also pink, baby blue, and black) are from that time period, and the 3x3 inch tiles were generally used in pools, kitchens, and bathrooms. So this may give a help as to how old these pools are. I recognize them due to being from that era.
Getting shilly in here.
Iv'e been awake since 1964 when they murdered my President. I'm a boomer. Fuk u, your mother should be whipped for giving you birth.
But for the 'plastic' child's sunglasses. 1960's on that one. I thought it odd that all the children are 'similar', i.e., headbands (again 60's) hair style, even the boys. Almost cookie cutter in appearance then that is broken by the sunglasses. Well we do need to account for artistic license. The artist may have a thing for that era.
I would really love to take some of this "art" and roast some open fire popcorn with it. You know, just the ones like Jesus in urine, a child on a bed being raped…the good stuff. But that would be against 'free speech' wouldn't it.
