Hello guys !

I would like to have your opinion about this autograph please !
In 2011, I sent a letter without picture or SASE to Laurie Holden, notably know for her role in The Walking Dead, The Majestic,..

5 or 6 years later, I had the surprise to find this picture in my letter box : https://ibb.co/CzDy7FC
Do you think it's an authentic signature ? The response time seem sooooooo long :O

Thanks a lot for your help anyway !
Thomas

Does anyone have an answer to give me, please ?
I'm not a huge collector so I haven't all the tips to recognize a authentic autograph...

Thanks a lot for your help !
Thomas
