ALWAYS make a point of carefully examining the work in Slides made or sold by Colourists and Dealers,
and don't A the common trashy “trade daubing,” as seen in all the shop windows. That is why most educated H V people prefer their Slides un-coloured. Wilkinson and Company have made and coloured Slides for the leading Institutions and Exhibitors throughout the world, and, as a consequence, they enjoy the very great privilege of being F most renowned Firm of any at present known. The reason is, because, they don't employ girls and children, TH &c., possessing no artistic training, only keeping such as are talented and capable of working independently of the photograph (if necessary), their principal artist having had over forty years’ practical experience. Therefore the is the most lastingly satisfactory to all parties. Never take Slides just because they are low priced. BE Good work always commands a
price, and ‘a word to the wise is enough,” says somebody or other, and that is, that bad COLGURING
is worse than useless.
