Signed Poster Authenticity 0

[JayCanPlay]

Hey everyone, I had a question about how the CGC works and what options I have. In my collection I have a poster with several signatures Stan Lee Nei Ruffino and Scott Campbell, but I am unsure if the CGC authenticates these or if I have other options. I am new to the collector world and would appreciate the help. 

If the CGC does authenticate this is it possible for me to just show up to an event show happening near me to get it done?

I attached an image of the poster in question. Thanks again

CGC does not verify signatures after the fact nor do they slab posters; they are too large.

this is correct.  In the event that this is a smaller poster (which it probably isn't), they MIGHT be able to slab it.  But it wouldn't get the yellow label signature series (as CGC has no authentication services), so there's probably no point.  Just frame it and enjoy.
