Hi everybody

I dont know if anyone can help. I have just bought this picture. They tell me its about 40 to 50 years old, when the restaurant opened. What I do not know is if it is a genuine official Guinness picture or a reproduction. It has a few cracks but that adds to the charm I think because of its age. I paid very little so if its a reproducton its not the end of the world, however, I would prefer it to be an official product of course!

its more than 1m tall. Ceramic.

Thanks

Jon

PS I would love to attach a photo and I have tried jpeg and .pdf and neither are accepted. What format should it be? thank
