The International Fine Print Dealers Association
The International Fine Print Dealers Association (IFPDA) is a non-profit organization of leading art dealers, galleries, and publishers with expertise in the field of fine prints. Members are committed to the highest standards of quality, ethics, and connoisseurship, and to promoting a greater appreciation of fine prints among collectors and the general public. Since its formation in 1987, the Association has grown beyond its original five founders into an international organization with over 165 elected members in thirteen countries. Membership requires a high level of expertise, ethics and professional integrity. Election to membership takes into account years in business, the quality of art offered for sale, exhibitions and published catalogues, as well as community service.
I have used these exact brushes exclusively for over 30 years teaching art to students from kindergarten to college. They hold up extremely well, if washed properly. They also hold a point and can handle a lot of paint at once. If taken care of they can last for years of continuous use. Students appreciate their quality and get much better results with a higher grade of brush, I cannot believe that Loew-Cornell has discontinued making them; so get them while you can find them.
