Which are correct:

1) He did paintings and statues, for which he became famous.

2) He did paintings, and statues, for which he became famous.

3) He did paintings and also statues, for which he became famous.

4) He did paintings, and also statues, for which he became famous.

Do '2' and '4' imply that he became famous only for his statutes?
Could '1' and '3' be used if he became famous only for his statutes?

If one eliminates the comma after 'statues', which sentences would have that implication?

Gratefully,
