I came across this Canadian booklet ,no idea where it came from but what I thought was bad foxing on the back of the stamps ,I don't think is on the stamps .It looks like a interleave that is stuck to the stamps .
Question ,did this booklet have a interleaf as when I hold it up to the light the perforations seem to be covered.
I'm relying completely on my memories of a 7 year old raiding the kitchen 'junk drawer', mailing off requests for those treasures found only in the pages of 1970s comic books.
I don't recall there being an interleaf on any of the Centennial series stamp booklets, or the 1962 cameos either. There certainly wasn't on later booklets either.
Thank you guys .Now what to do with it ? explode it and soak the inter leaf off and have a mint no gum booklet pane?or leave it as is .
Your thoughts please ,as I know nothing about Canadian stamps.
