It appears someone has removed the protective sleeve from a slide in
the Alpha Folio. I know this, because at least one of the slides that
are now missing sleeves was mine!

I must stress that removal of slide sleeves from the original slide is
strictly forbidden in the Alpha, Beta and IMFSF folios. You must
respect the participants right to protect their one-of-a-kind original
slides. If they are damaged or dirty, contact the owner of the slide
for permission to clean or replace.

Thank you.
