Three parts

Left, Right, and Centre. That way the fuzzy inner edges where I had to curve the paper were scanned again in the central part, and all I had to do was stitch it all together again. I managed to scan the middle section only by very gently curving the ends around to the back of the drawing, so that it was belly down on the scanner with the ends curled up either side - but most definitely not creased in any way.

Pleeeeeeeeas don't cut that lovely drawing in half!!!!
