Fantex, offering NFL player Vernon Davis tracking stock, has taken to Twitter to promote its offering.  The required legend to use a free writing prospectus, or FWP, would exceed the character limit imposed by Twitter.  However, depending on how you view Twitter, the legend is either accessed by clicking an “expand button” or a link to a picture of the legend.  Note also the link to the prospectus and that the prospectus includes an offering price.  See Rule 433.
