How the critical stages of the pandemic were reflected in urban LLs is also in focus in the eighth chapter, which presents a study of crisis communication through unofficial signs in Helsinki and Stockholm. The discussion is about how different rules and recommendations were communicated and legitimised on unofficial signs in the signscapes of both Finland and Sweden. Based on a combination of sociosemiotics, discourse analysis and translation studies, the study gives insights into the role of unofficial signage in the dissemination of crisis communication, and how moral evaluation, rationalisation and authorisation are used as legitimation strategies in transmitting official COVID-19 regulations among the unofficial layers of urban LLs.
