These banner ads were used to promoted AvKids.com, a web site aimed at educating students and teachers about career opportunities in business aviation. AvKids.com is sponsored by the National Business Aviation Association (NBAA).
The smaller of the two banner ads was used on the NBAA home page (www.nbaa.org), and the larger ad was used on a CD-ROM of NBAA's Membership Directory that was mailed to NBAA Members.
I am the web site designer for both sites.
