Since this came up again in my mind I did some quick research cause didn't we also have a little thing called HR 4472 along with 2257 amendments? Sure we did. A quick review of sources including
http://www.xxxlawnet.net seems to come up with the general guidance that 2257 info should be placed on every page where a covered depiction is placed. Secondary producers also got reincluded in new language and if are not a member of the FSC are not covered by the temporary restraining order. Bottom line if you want be safe include it on all pages with pics and then consult you lawyer. Wouldn't it be nice if more were members of FSC?
