Damaged Prints Repair

Hi guys!
Recently, I’ve had issues with the arrival of both slightly damaged canvases and foam prints being delivered to me. I do raise it with the printers and replacements are sent, but this can take up to two working weeks.
I was wondering if there are any ways that damage such as I show here can be quickly and easily repaired? I am considering trying colouring pencils.
