What of the A21B or AZIB scratched on the base of the toy car's mount? Like the red dot on the box we no longer know how to decipher this code so I've imagined a number of scenarios in which we might need to allocate a number to the object. I've then taken this number and this scenario and found other incidences of the number and scenario coming together somewhere out there on the internet. So do take a look at the accompanying images and pair up the numbers:

1- Was this the evidence number in an ensuing legal case?
2 - Did it ever appear on a menu?
3 - Was this car ever public transport - Public Car Route no. A21B?
4 - Is Azib in fact the child's name and he wrote it on the box to stake his claim?
