Sketch Drawings from 1920’s Album

These beautiful hand coloured sketches are all mounted in a large hard back book and were drawn in the late 1920’s. They vary quite a lot in size so have been split into two books and the portrait pictures have been sized to a common vertical size and the landscape pictures to a common horizontal size for ease of viewing. One or two of the pictures that are included are photographs that have been amended or had dimensions etc added.
I can only assume that these ‘sketches’ were used for decision making over product designs. Some are certainly products that were produced.
