Not a full language, but rather a limited pidgin used for cross-linguistic communication, especially at international meetings such as those of the WFD and the Deaflympics. Distinct lexically from all specific sign languages, as it incorporates elements from a variety of different (mostly European) sign languages, and shows considerable variation depending on the location where it is being used and the L1 of the interlocutors. Fingerspelling system similar to French Sign Language [fsl].

The listing of International Sign under Italy is semi-arbitrary, but necessary since Ethnologue is organized by country.
