The recipient can write Real Madrid Club. Generally, big clubs will have special fans' letters ... there may be no gifts, but it may take several times to receive a reply. Real Madrid has fewer gifts. I sent it several times in high school and received a family photo with Real Madrid's signature on it. Unfortunately, the signature is printed and there is a very official reply ... If you want some gifts, you'd better find some small and medium-sized clubs, which will bring you unexpected gains.
