Upholstery for Bluesmobile bench seat

[scmods55]

I’m going to have the seats re-upholstered for my Monaco.  I recently saw a 74 Monaco Police Package originally from Georgia with what looked to be original interior and it was completely plain...no design or anything.  To be “movie accurate” should I re-upholster just with camel colored vinyl and no design?  Are there any pics of the Bluesmobile’s interior?  Any suggestions would be greatly appreciated.

Thanks,
