Posted on a teadete/tahvel (bulletin board) in the village of Pärsama on Saaremaa island. OÜ = osa/ühing, i.e. limited liability company, while Koikla and Räägi are two neighbouring hamlets. Lüpsi/kari literally means "milking herd" and lüpsma to milk. Karjak is a gender-neutral term for a herder.
More well known historically are karja/poiss (herder-boy) or -tüdruk (-girl), karja/mees (-man) or -naine (-woman) or simply karjane.
