These, children, are what used to be used just after the invention of the Magic Lantern and before the arrival of the Powerpoint.
The slides both outside and inside the box must be at least 50 years old - does that make them vintage or antique? And the eagle eyed may spot that most of them are in colour :)
I can tell you, because it's not obvious, that none of them are of the Agfacolor brand shown on the box, which just happened to be handy when they were put being away to store.
But now they are out of the box - needless to say I can't find my slide viewer!!!
Long evening with the scanner in prospect then... Well, it makes a change from the O word.
