Unlikely part of a healthy breakfast: While lightening the load on my creaking bookshelves, as I try to do every year, I pulled out an old Cardinal paperback (cover price, 35 cents) of Arthur C. Clarke's The Exploration of Space. In it was this trading card (c. 1959) depicting the GAR (guided aircraft rocket) Falcon, number 24 in the "Defenders of America" series.
Originally included as a giveaway in someone's box of breakfast cereal, this card was later tucked away as a bookmark and, eventually, forgotten. It's unlikely, then, that the original owner was sufficiently motivated to "get the entire set," as the card encouraged, "by eating Nabisco Shredded Wheat regularly and trading with your friends."
