Deep Purple Machine Head autographed?

[peace brainerd]

I've never traded or "collected" vinyl - and have no ambition to.
I pick up a lot of stuff at garage and thrift sales that I'd like to listen to. I just got around to dusting off a dozen albums I bought this spring and noticed that Machine Head by Deep Purple is autographed by all the members of the band.

Is it worth my while to have this authenticated? Or not a big deal? I have no idea where to go online to investigate this stuff but I've been a member here for a few years so I thought I'd just toss it in.

Thanks for any advice.

It could be worth some money.....
Machine Head was their really break through and most popular album, so if the autographs are authentic, a collector may want to pay $$$$ for it!

If not, you can mail it to me
