T207s: Haze on the glaze
 

When T207 brown borders are found in great condition, they are truly a thing of beauty.

Some have withstood the test of time better than others, with very little cracking to the glaze surface on the card fronts.

Whereas, others have developed a "hazing to the glazing."

Anyone have a theory as to why some have become cloudy with regards to the glaze surface?

Is it moisture, sun, bad glaze or all of the above?

Thanks,

Patrick

I am going for the first two, being the environment, causing most damage. They really have a great finish to them when they are pristine. (and I know some are print errors but I don't think that is usually the reason)

Heres some beaters I just picked up today . Seems like the finish is crackly or almost leather like . Maybe they were meant to look like that with the Brown background .
