In the case of a painting of unusual artistic value, a work that has not been put upon the prohibited list of the official catalogue, and the reproduction of which is unknown to the authorities, but which might, nevertheless, by its good qualities catch even the generally inexperienced eye of the inspectors--mostly art critics of the literary species--the work is transformed into a daub without damage to the painting or change to any essential part. The process is exactly the reverse of that helping a poor painting by clever restoration and additions. Here it is a question of reducing a good work to an apparently bad one, obtainable chiefly by veiling the good qualities of the work, altering good drawing by cleverly introducing offensive disproportion of limbs, etc. There is a difference, however, between the work intended to embellish a painting and that aiming to do the reverse. The former, with the idea of facilitating the sale, is permanent, the latter is only temporary, just to get permission to export. This latter work must be executed in such a way that it can be washed out without damage to the work after the painting has safely crossed the frontier. For this operation a coat of glue is generally given as a preparation, then the modifications are painted in with tempera on the layer of glue, which is easily dissolved in water, together with the retouching when the work is to be restored to its original state. Similar treatment is also given to statues, busts and bas-reliefs, more especially when of material that allows the addition of parts that can be removed afterwards without damage to the original. How well the work is done and how successful it proves is hardly credible. Security lies in the fact that should a question be raised afterwards when the work has been sold to some noted collector outside the country, nothing can be said or done, as permission has been granted and there is no pictorial proof that the work had been done for the occasion. Naturally this method is not of daily or common occurrence, nor, as we have stated, can it be applied to well-known works the photographs of which could be obtained to contradict evidence. Sometimes more is undertaken than retouching or apparently maiming the artistic qualities of a work. One antiquary who intended to send off a painting that might be detained at the Export Office, pasted paper over the picture, and then after the usual coat of glue painted in tempera a very mediocre landscape. With this he obtained the export permit and packed his work as prescribed by law before the eyes of the authorities, after which the case was sealed by them and safely sent on its way to the frontier. Leaving the endless tricks which might be grouped more or less with the above we will take up other curious ways of eliciting permission, methods showing the deceiver to be as good an observer of human nature as he is a true psychologist.
