Does it hurt the value of a collectible magazine if you black out the address label?

Collectors and dealers: advice please.

I’m looking to unload a quantity of Omni magazines (details here ) that came into our house as a subscription. We haven’t moved since then, so they still have our name and address on them.

If I take a Sharpie and obliterate the address label, does that affect the value of the item? Is that a point that I would have to disclose to a prospective buyer?
