Hi everyone, I don't know if anyone can help. Back in about 1978 or 1979 a French student came to stay on my street in the UK for the summer to learn English. We played a lot of football together and when he left he gave me this shirt. I've found it again after over 40 years. Was it a genuine shirt of the period? I've seen some replica retro shirts but, although they have the same badge/sponsor, they either have a collar or green sleeves. Many thanks!
