*On the inside photo, Paul is wearing a patch with the letters "O.P.D.", interpreted as "Officially Pronounced Dead." According to John Neary, this phrase is the equivalent of "Dead On Arrival" in British police jargon.*
Now while I'll agree obviously it started life as an O.P.P badge
It certainly looks like they added the yellow changing the P to a D adding to the whole grave site scene on the Album cover
Add to that
The Japanese stone figure
The rest of the Beatles are standing at an angle, Paul is facing the camera as though he were being supported by his bandmates standing at his sides
The Beatles are all holding Brass band instruments, but Paul's is black
The Left handed Bass Guitar on the Grave with only 3 strings not 4
The cloth grandmother figure, on whose lap the Shirley Temple doll is resting, is wearing a blood stained driving glove.
and A model of an Aston-Martin, the type of car that Paul was supposedly driving at the time of his fatal accident, is leaned against the doll's leg
I think it's painfully obvious
No one here cares how many different vehicles the O.P.P has in it's undercover fleet
