Among the objects recovered from the funerary site of the Laguna de los Cóndores were 32 quipus, the knotted strings the Inca used for record keeping. This is largest number of quipus recovered from a single site.
To keep things simple, the Inca did not have a writing system, but they did record information on knotted strings called quipus. While it's clear the quipu recorded numbers, it's far from clear how the Inca knew what it was that was being recorded.

From the Museo Leymebamba in Leymebamba, Amazonas Department, Peru.
The museum's web site states:
Inaugurated in June 2000, the Museo Leymebamba displays the more than 200 mummies and their burial offerings recovered in 1997 from the Laguna de los Cóndores by a salvage Project directed by Centro Mallqui. Once at risk from looters and vandals, today this valuable collection is housed in the Museo Leymebamba. An initiative of The Bioanthropology Foundation Peru-Centro Mallqui, the Museo Leymebamba’s construction was made possible by a donation from a group of Austrian citizens as well as by funds from private donors.
