The treasure trove of art that is presented in this volume for the first time lay dormant and unknown in the depot of the state museums of Tyrol for nearly 200 years. More well-known collections of graphic prints generally store such works mounted in passe-partouts, on which there are occasionally brief, at times cryptic-seeming annotations, in which art experts jotted down their proposed attributions. For the still unexplored holdings in Innsbruck, such a scholarly discourse, which was often conducted on passe-partouts over decades, was initiated quasi in time lapse. This publication brings together annotations jotted down by experts on the passe-partouts of the drawings, which are presented here for the first time. This thus offers fresh insights into the practice of the forming of expert opinion.
