View Master & heaps of "wonders of the world" 3D slides.
I had a View Master as a kid & I loved it!
I obviously never got the 3D thing because I don't remember being as amazed then as I am now. I really want to walk into the scene on Bondi beach & pull up a towel next to those 1960s bikini clad girls.
Thrifted from my favourite Op Shop last week.
