Hi, I purchased this from Boston memorabilia. I'm not really sure to think of the website. It seemed a little more legitimate than others I've seen, but still doesn't answer all the questions I might have. So I'm not sure what to think about the legitimacy of this autograph. 

In the plus column, looking at many photos of band signed albums from Van Halen and especially focusing on David Lee Roth. A lot of the idiosyncrasies in the signing do appear to be similar to what I'm seeing here. Dave has a large d and is usually a loop somewhere in the L. A lot of the way he signs. It seems to be similar on many other albums I've seen. I'm less familiar with the other band members. 

I know coas are generally not worth much, but for what it says, it says that the band members other than Michael were signed in 2015 in October. Michaels was obtained in February of 2016. I do think it's plausible because 2015 October the band had their last shows of the tour. It says that the autograph was obtained in Los Angeles which is right about where they had their tour stop on that date. So I guess my thinking was someone who could have backstage or after show access cuz theoretically get this signed. 

Here are the photos I have of the album. If you need me to take anything else like something more zoomed in to help assess please just let me know.
