What's this biplane built by a 16-year old?
I don't know about this being from the 90s, but it sure looks like the Laird Baby Biplane in the Florida Air Museum to me:

The identifying features that I observe to be common between this picture and other pictures of the aircraft are the shape of the nose, the details along the fuselage, the shape and placement of the struts, the tanks beneath the top wing and the shape of the engine protrusion. I would also note that the Wikipedia page indicates that the specimen in the museum is a replica that was built in the 90s (whereas the original is from 1912).
