This symbol — known as the infinity symbol or the Möbius strip — was introduced in 1967 and was used by most cooperative activies for the next two decades.
By the early 1990s, KF had sold many of its subsidiaries and had been transformed from a large conglomerate to a company mostly concerned with consumer retail.
In 1995, KF adopted a new logo, which was known as; most stores had abandoned the infinity symbol by then and were using separate identities. As the new logo would only symbolise KF, the two letters became a permanent part of the logo.
In 2001, KF introduced the brand Coop as a collective name for all their stores, and the KF name and logo fell somewhat out of usage; however, it remains the logo of the cooperative union.
