"In all cases where a garage keeper is not a warehouseman, the common law gives him no lien for storage. A garage keeper who retains possession of a repaired automobile until his bill for repairs is paid has no common-law lien for storage."
"Neither is appellant entitled to a lien for storage under [the relevant Wisconsin statute]. Before a garage keeper can enforce a lien for storage under this statute, he must establish that he has 'posted in some conspicuous place a card, stating the charges for storing the aforesaid automobile, the same to be easily read at a distance of fifteen feet by any person entering the aforesaid garage by entrances.' There is no proof that the sign which the defendant testified that he posted complied with the requirements of this statute. It follows that he had not established his right to maintain a lien for storage."
