This was a sister publication of American Heritage. Sold two articles just before they ceased publication. It was always nice corresponding with AH on Fifth Street in New York City. I&T has recently resumed limited publication in hardcopy and they have several new issues online.
My article on cell phone history in this issue made the cover and was the lead article.
Invention & Technology: Summer 2007. The Cell Phone Revolution.
Invention & Technology: Summer 2008. Gold: From Panning to High-Tech Mining
The magazine staff did an incredible job of illustrating my text.
