I have a product called "The Last Grey Card". It was made by Unicolor and its 10x8 size is glossy white on one side and 18% gray on the other.

It is at least twenty years old and today to my eyes it looks tinged with brown!

Is there any method where I could determine if it really is still 18% grey?
