Robin -
I have some idea of years, based on the price lists, and the guy I bought them from kept track of the years on the envelopes. I think it is also possible to derive the sequence of issue from the catalog changes of offerings. Can I post my estimated in the comment section of your album, or should I start another album.
If anyone else has any info on years of issue, I would appreciate it.
Thanx,
Billy
