We can authenticate your autographs. However, if you are looking for authentication for purposes of selling, we recommend using a recognized service like PSA/DNA. We are regional representatives for PSA/DNA. We bring the experts who can place PSA's authentication hologram on your item to Detroit area a few times each year. Check our calendar or sign up for our email list for more info on dates and times. If you need authentication for personal purposes, we are more than capable of handling that for you. Just schedule a time to come in to our showroom in Waterford
I have a signed / numbered poster size lithograph of Sparky Anderson. I see you recommend PSA/DNA for authentication for purposes of selling. It looks like they authenticate "cards". Are there other recognized services that authenticate signatures on poster sized memorabilia?
