This is Greg sitting at DFW airport watching a plane come in for a landing in the distance. It is a very small gum printed on the bumpy side of the paper. It is gum over cyanotype, though the cyanotype faded to a murky tan color. I experimented by spraying a coat of clear acrylic spray paint over it to give it a glossy look. It takes quite a portion of spray, as water color paper readily absorbs most of the spray. This print smelled like fumes for months!
