Hi Gadge,

I appreciate that information. It makes more sense now.
There must be a double layer on the slide I have - it is not on the outer face of each side.

I am surprised you have this knowledge - of slide projectors and the like!
For me, the fascination is that this slide - from Victa's earliest days - was projected
to a small audience in a small-town during Victa's halcyon days.

I guess it's a Woody Allen The Purple Rose of Cairo thing for me . . .

p.s. if you have any collectables, please feel free to share them in this forum.

All very theatrical.
