Can someone shed some light on what this is? m It appears it was used to test the ink or color in some way. Thoughts appreciated. Left to right - front, open, back

Possibly to test the colour fastness in the presence of light over various duration hours.
Just a guess from the wording and open part of the folder.

It is listed in the Scott US Specialized catalog as a test stamp. Quite a scarce item.

Thank you Smuggie,

A pleasant surprise. Would never have guessed 1970's. Back to see what else is hiding in the box
