Back in the 70s my parents had this enormous mod cityscape sofa print in their living room. It was yellow and orange, to go along with our orange printed sofa, orange curtains and orange shag rug...yes, orange is a favorite color in my family! Around 10 years ago I had spotted a similar framed print at a vintage store, which was green and blue, but they wanted $200 for it, which is outrageous! I'm sure that my parents only paid around $20 bucks for theirs! Sadly, my parents ended up selling theirs at a yard sale when I was in college.
This is the best photo I had scanned of the sofa painting. Sadly, the scan shows a white mark, but you can see that it is a modern cityscape.
While researching I did come across Carlo of Hollywood who did a number of paintings in this style. Not sure if this is a print of one of his works, but it looks quite similar.
Sadly, there is no way to confirm whether or not my parents had a Carlo print or not because its gone now, and the photos are not clear enough to show any signature. My research continues....
