There are no rules; no guidelines; no criteria for selection, no test to veriy the qualifications or correct understanding of a judge used for these shows (most involving paniters and judges from sevaral countries ). All is matter of friendship, blind trust, or 'being known'. Should be apply this in pharmaceutical, car, aircratft matters to evaluate quality of a product, the judges would disqualify them selves quiet immediately for being untrained and unqualified. But this is hobby world of a small community.
It is to the community itself to setup their own régulations for such activity; not difficult, just be willing to do so for correct evaluation, fairness. This "society called 'international flat figure society ' is perfectly fullfilling the profile of such an organisation to setup some simple , clear and useful guidelines for judging flats in international competition. Many members are master painters with experience, contact and across several countries to come in one year time with such guidelines and improve the skills not only of painters, but other judging ther work. Kulmbach should be a deadline to annone and publish such guidelines.
Just need people willing to take this over, not just complaining for absence.
(I think, at least, ... but I am myself still between a novice and confirmed painter ...)
