The German 'Philistine Collector' Petition has lots of signatures from people who don't want to buy due-diligence antiquities. The "Support Responsible Antiquity Collecting" one, not a single signature. Not one. What does that tell you about collectors?
See here PACHI Monday, 27 July 2015: Who Will "Support Responsible Antiquity Collecting"?
The exercise seems to have backfired, its creators seem to have wanted to create the impression that there is a groundswell of responsible collectors out there who are opposed to the philistine tactics of their fellows. The effort falls a bit flat though when they cannot get a single collector to sign up to it!
Are there any ethical collectors out there anywhere in the English (or even German) speaking world that would like to declare themselves in favour of artefacts accompanied by documentation of proper due diligence? Or are they afraid to put their head up over the parapet?
