The original Danny and the Cruisers album coverlike photo, above, was apparently such a hit that General Motors decided to re-create it.

The below version — released last month with the announcement that Dan Ammann would step down as GM president to become GM Cruise's CEO — is marginally more formal, with the sport jackets and all.

It perhaps signals that GM's autonomous vehicle subsidiary has entered its grown-up phase.

From left, in both photos: Cruise co-founder and COO Dan Kan, co-founder and current CEO Kyle Vogt, and Ammann, who will take over as CEO on Jan. 1, while Vogt becomes president and chief technology officer.
