Any Comic Fans Here?? Help Comic Art Please.

Hi everyone, I picked these prints (posters) up today at thrift store. I paid $10 apiece for them. I believe they are from some comicon show or something like that. They are all hand signed by the artist. I could only find one on Ebay and it was listed at over $100. Are these prints (posters) worth that much?? Thanks in advance.

 

These look like self-produced fanart posters. The one on the bottom left is by Gavin Smith. The prices are all over the place. I can't tell you where these sit.

 

Here's the Supergirl image. You can see how it compares to yours and if you have an account there you can see the sold price.

Thanks smallaxe, ya the prices are mixed. Plus i can't make out all the different artist signatures. I bought 25 of these things. Thanks again

 

I believe it is the same one, it is signed Ambruson. Thanks so much!!

 

The worthpoint one sold for $14.99.

 

It looks like Scott Ambruson signs his Supergirl poster pretty much the same across near the bottom.....pretty large siggy....
