1964-65 World's Fair Double Sided Puzzles - Unisphere, Monorail, Fountain, Pavil

Description

These are in used condition.  So please check the pictures closely.
The Pavilion has the most wear to it.
The monorail and unisphere both have at least one piece each that is showing cardboard.
These come from a smoke free home.
If you have any questions, please feel free to ask.
I will combine shipping.
Thanks for looking!
