Graded drawings for infants and junior classes
A graded drawing manual by Anne E. Roberts, published by Blackie & Son in London in 1900 for infant and junior school classes to copy from dictation. Numbered plates divide each page into red-ruled panels holding single-weight line exercises: crossed diagonals, circles quartered, nested triangles, rhombi and cruciforms, usable as spare geometric marks, grid layouts, or diagram borders.
