Canarian researcher Fernando Estévez González, who died in 2016, is the author of the posthumous essay Souvenir, souvenir. An anthropologist before tourism (2019). "In the pomp of tourist consumption," he says, "the souvenir represents the embodiment of useless spending. As the main symbolic medium of tourism, this small memento, produced in bulk, cannot hide its banality, but it contributes to making the intangible experiences of the trip tangible."
