I wanted to buy 2 autographed photos for my teenagers for Christmas.  I bought these two items on Ebay before finding your site (wish I had found it first!).  I have received the first one and I am not sure if I made a mistake.  The photo is laminated and has "walgreens 05602 04/04/14" printed on the back.   I have 15 days to return it so I don't have time to send it off to an authentication service, even if I knew which one to send it to.

The listing of the first one that I have received is http://www.ebay.com/itm/231715247479 

The second one for David Tennant is

I don't want to give my kids something they think is real if it isn't.  Any advice is appreciated.

Thank you.
