The individual cards were stapled to the board, and were ripped off when someone wanted to purchase one or more of them.
This of course resulted in the actual card of wire having a torn hole in the top.
Three values of wire, 5A Lighting, 15A Heating and 30A Power.
Switch off at meter before renewing fuse - rather confusing, since electricity meters do not contain switches, and it is entirely possible that the fusebox and meter could be in different locations.
The back of the card is plain.
