Look a little closer
Leather objects may have surface treatments and different visible textures. A smooth or embossed appearance does not give a complete account of the underlying material or its condition. Historical leather also requires a different handling context from an everyday product.
A note for your design book
Describe visible grain, sheen and wear in separate notes, then add the declared material and finish information if available. Do not use a photograph to assert species, authenticity or grade. Canadian Conservation Institute guidance is intended for caring for collections; consult the actual maker’s instructions for everyday use and an appropriate conservator for a fragile historical object.
