Pochettes are small instruments of little interest. Completely wrong! In Joachim Tielke's oeuvre they provide important confirmation of the suspicion that he put his label in work from other hands. It is evident (in TieWV 5 from 1671 in the National Music Museum, Vermillion, South Dakota, and in TieWV 103 from 1699 in the Jihočeské muzeum v Českých Budejovicích - Museum of South Bohemia in Budweis/Czech Republic) that he ordered instruments from Paris and squeezed his own label through the soundhole; the paper is crushed in several places. A paper on this matter has been published in the Galpin Society Journal of 2009.
