Our research in the collections brought us to reveal links between the formerly private collection of Ulli and Georgina Beier and the collections of the Náprstek Museum in Prague. In February 2017, senior researcher Katharina Greven and junior researchers Lena Naumann and Siegrun Salmanian went to visit the custodian of the collection, Jana Jiroušková and could confirm the strong links of the collections. In the early 1970s, via diplomatic transfers, the Beier’s collection travelled to exhibitions and Europe, one important point was the ethnographic museum in Prague which never saw a contemporary art exhibition before and which focused on a progressive program under the directorship of Dr. Erich Herold. Interesting is, that parts of the formerly whole collection ended up in Prague – first as permanent loans, later as a donation. This part of the collection is complementary to works preserved in Iwalewahaus collections and includes pieces by Asiru Olatunde as well as a series of behind glass paintings from different artists from Benin as well as some hardboard paintings and a few calebasses. These works were formerly longtime exhibited in the Museum of Popular Art in Oshogbo.
