The Cottage definitive Callcard was first produced in 1991 and was still in production by the end of 1995. As a result many different variations of the Cottage Callcard exist. Schlumberger produced many different print runs with different chipsets, addresses printed on the back and also more subtle varations such as visible holes on the back of the chip. While many variations do exist, only some of those variations are shown on IrishCallcards.net.
Some early Cottage Callcards never came wrapped.
