Will BA white covers turn brownish? 0

[Chaos_in_Canada]

I have three comics with varying whiteness (back covers).

SA(1966)-Left, BA(1977)-Centre, BA(1975)-Right.

All have white pages.

Will the two BA back covers eventually turn brownish, like the SA comic?

Not if stored properly.  Avoid temperature swings and environments either too moist or too dry.

Living in Canada...probably not. I live in Florida and have to go to great lengths to keep the temperature and humidity at a constant where I store my comics.
