There are two companion advertisements/posters. The most commonly seen one is where the model is sitting next to a set of speakers and the sound is apparently blasting his hair and clothes back. The other photo is of the "exploding" targa top. The first one is fairly easy to find and isn't all that expensive because Maxell owns the rights to the photo and they license it periodically for reproductions. Steigman kept the right to the Porsche photo and neither he nor his estate have licensed it for reproduction. Apparently he licensed it to Maxell for the ad campaign and kept the rights afterword. So all of the Porsche posters are original to the ad or the poster that was sold or given away briefly without the ad copy when the ad campaign came out. That's why the Porsche posters are rare and expensive.

For what it's worth, the estate holds the rights to the Porsche poster and enforce the copywrite. I don't know if a commercial copier would object or not.
