I tend to think it is fine for a couple of reasons. Mays had a contract with Steiner many years ago before he had health issues, so the signature would be nicer. With a paint pen, it will bleed very easily on a jersey number if there is any hesitation in the signature. If there are no stop and start marks, which there aren’t, then it would be a nice flow to the signature, which it has. Lastly, as long as the Steiner hologram doesn’t show any little dents where it may have been lifted or peeled off another item and placed on this, then you are good for sure.
