I've been doing jigsaws for many decades. Before my grandmother died she gave me two 1950s puzzles which will go to my cousin along with other family treasures. I sent all my jigsaws to charity shops a few year ago (many of them came from charity shops!) Unlike my jigsawing friends, I only have one table in my apartment so it needed to be cleared to puzzle, & bending over did my back no good.
So now-a-days I do oonline jigsaws I only kept 2 puzzles, one is a cheaply made war time puzzle of General Macarthur & Battle of the Coral Sea (probably a fundraiser), the other is a good quality puzzle from 1954 of Queen Elizabeth's coronation.
