Approvals
Having bought a bunch of Poland cto's and found most of them curling, ( but unlike GB no gold medals) I first spent a few hours sorting into years of issue. Tonight I started soaking them and drying by year order. Should take me a week or more, but at least I will be rid of the old hinges and hopefully they will stay flatter when mounted.
Must admit I really do hate the proliferation of Eastern European issues with no real reason other than to generate income.
Why do we give ourselves such a lot of work, who knows, I guess it eats up a bit of time and stops the grey matter solidifying.

re: curled cto's

Yup, I just received 362 DDR from Jan-Simon (siem) today, and they are still sitting on my desk. Just minor curling is all I see of the lot. It will keep me busy, even without your kind of curling!

re: curled cto's

This is also the case with Romania and Russia. I would do the same thing - soak them, let them dry and then put them in a stock book that will make them flat, for the most part. Some stamps have a type of gum that doesn't completely come off and leaves a shiny film on the back of the stamp. These stamps tend to curl up again.

It is a problem since the Polish and Romanian stamps from the 60's-80's are printed on weak paper where the corners will easily be rounded or destroyed if a person is not careful with the stamps.

CTO or not, I collect certain periods of the Eastern block, mostly out of nostalgia.

I received a number of British commemorative from the 60's and 70's recently, and the curling on all four sides downward was astounding to me. I've never seen stamps curl like that before! Did the Brit's use weaker paper in that period too?

re: curled cto's

Its not weak paper its down to the gum having a different expansion and contraction rate from the paper.

Gum hardens over time and become less flexible.

It all depends on humidity when the stamps were produced, when and how they were stored, and when and where they are "released into the wild".

Soak the #$%^&* gum off and hinge the buggers.
Does the presence of original pristine gum really
add anything to the collection page ?
