I've done a little more "Ausgeflingen."DON'T ask why I still have it.
     In an earlier incarnation I worked at U. K. A. E. A. for a few years.  How I come to still have it in my possession totally defeats me - BUT after a mere 50 years I can't see anybody sending round the Guest Appo.  ;¬)
     Apparently, after developing the film they would be able to assess how much of each type (IF any at all) had been absorbed by the wearer.
     I notice, but don't show, a similar layering inside the back thus they could calculate how much (again IF any) came from in front or behind.
