So you would love to collect art but are low on $$$? No problem! During the next three days, you can make barter deals with artists for their work. How? well, in pastArt Barter events, original artworks were acquired in exchange for 3 months of therapy, French lessons or webdesign, for example. 26 Berlin based artists will be bartering for their works from June 24-27 at .HBC. Opening tonight!
