need some help from the experts out there. i recently purchased a serpia panorama of the 1916 chicago white sox, and while it is in fair to good condition it could use a little cleaning. i don't want to get it restored thinking that would take away the valve of it. all i would like to know is ,should i try to get it cleaned by a professional, or leave it as it is? if i did decided to get it cleaned would it take away the valve of it?? thanks for any and all help

UPDATE: I have pictures of this picture but they are too large 5.2 MB. Does anyone know how upload these pictures. I've zipped them and they are still too large. Thanks for your help.
