Knife And Leather Drawings, Mark Evans

Leather is used exclusively by publishers like The Easton Press to bind books, for both practical and aesthetic purposes.
Religious sensitivities to leather
In religiously diverse countries, leather vendors are typically careful to clarify the kinds of leather used in their products. For example, leather shoes will bear a label identifying the animal from which the leather was taken. In this way, a Muslim would not accidentally purchase pigskin leather, and a Hindu could avoid cow leather. Many Hindus who are vegetarians will not use any kind of leather.
