Any piece I use in my portfolio is used as it aswas delivered to the client.
While I've been fortunate the last few years and have had considerable control over client revisions and changes, it's common practice for many clients to alter work later. Especially web work.
When showing my portfolio, I simply explain all pieces are as delivered to clients and alterations outside my control may have been made since the initial project was completed and delivered. Everyone seems to understand.
