I didn't realise that there was a relevant picture in the museum set -- 
http://museumofcommunications.org/wp-content/uploads/2012/06/DSC_7116-1024x680.jpg 
shows severak of those cards on shelves, and in the near fore-ground is 
the bins used for sorting cards for further investigation (one of the 
"investigation" steps was to take a deck of cards for a similar failure 
and hold the deck up to the light to see if a single piece of equipment 
had been involved in every failure (hole goes through the deck).
