Matthew did an amazing job getting a signature on my John Wick poster. Handling it with the best care and managed to acquire a signature from Alfie Allen without any hiccups! Shipped it back to me fast and secure. Maintained communication with me through the whole process! Will definitely use him for more in the future!

Two great finds from Matthew. Thanks!

Matthew Ambrose was a huge help at Film and Comic Con Cardiff as he helped get Guy Siner on my Seinfeld items. Great communication throughout and fast return shipping. I would definitely ask for his help again, thank you!

Have got plenty of very valuable pieces through Matthew over the last few years and his communication and dedication is incredible. Goes out of his way to make sure cast pieces are kept up to date if he is seeing people he knows you need, one of the best.

Matt has been a huge help to me in getting Harry Potter autographs for my collection. Totally trustworthy and a great guy to work with.

Started dealing with Matt in 2019 and have gotten a bunch off him since, always been great service and never had an issues with anything. Attached is my Jason Isaacs from his private signing.

Since getting to know Matt last year we decided to team up and launch the group Celtic Signatures, all customers can be assured that when buying from Matt they will receive top service.

Matt is a credit to the hobby, I've gone from being a casual customer of his many years ago - to a working partner with Celtic Signatures. With Matt you can buy with complete confidence that the items you buy are legitimate and that he will act as upfront and honest possible in any transaction. A credit to the racc community.

I got a fantastic Jason Isaacs (Lucius Malfoy) dedicated autograph from Matthew. The comms for the organised signing were great and he also provided helpful advise on picture and pen selections.
I've also bought a number of other Harry Potter autographs from him. Service was great each time along with updates on postage and quality of item packaging.
I've had a couple of conversations with Matthew following purchases where other he's shown me other items or allowed me to list autos that I'm looking for in case he has them or will advise in the future.
Top seller and I'll definitely return to buy more pieces in the future.
