A pronoun should also be in the subject case when it is in apposition to a subject or subject complement, and in the object case when it is in apposition to the object of a verb, verbal, or preposition:

[RIGHT] Three craftspeople -- Mary, Albert, and he -- made the accessory for Jerry.

The phrase "Mary, Albert, and he" is in apposition to "craftspeople," the subject of the sentence.

[RIGHT] The accessory was made by three craftspeople, Mary, Albert, and him.

The phrase "Mary, Albert, and him" is still in apposition to the noun "craftspeople," but that noun has become the object of the preposition "by," so the pronoun "him" is in the object case.

[RIGHT] The three craftspeople involved were Mary, Albert, and she.

The pronoun "she" is part of the subject complement, so it is in the subject case.
