Discoloration of photographs

I have a little information to add to Doug Nishimura's
posting (Conservation DistList Instance: 10:92 April 24, 1997).

Some time ago a friend of mine passed on to me a 'magnetic' photo
album with a similar problem to that described. The album would date
to the 1960's and was made in Korea. It spent most of its life in
Sydney, Australia--i.e. quite humid. The first couple of leaves of
the album display red staining that is associated with the (now
removed) photographs. This staining is in a line around the
photograph and in one case runs right underneath where it has formed
what look like mould blooms. My assumption has always been that the
staining was due to a mould, but just what the mechanism is I don't
know. I have not done any analytical work on the stains. The
staining is only heavy on the first page of the book--later pages
only have the odd spot.
