thanks for the insights H -

my uncle used to make dye transfers back in the 60s ..
and has some in his home that have been on the wall since they were made ..
they get outdoor light, over head light &C since it was made ( 40+ years ago ) ...
and they looks like they were made ... last night ...
i was always told that dye transfer was the most long lasting of all the color processes ...
it is good to know there are others that are as ( if not more ) stable -
