Nestlé's Doctor Who milk chocolate
From Tardis Wiki, the free Doctor Who reference
Nestlé's Doctor Who milk chocolate was a licensed product from the 1970s. At least two series of milk chocolate bars were produced by Nestlé. One was issued in 1971, coincident with the broadcast of season 8. This range offered fifteen different wrappers, each featuring a different installment in an illustrated short story starring the third Doctor, Jo and the Master, Doctor Who Fights Masterplan "Q".
There was at least one other known range, in 1974. It had wrappers featuring the fourth Doctor, Bessie and the Brigadier, as had been featured in the lone story, Robot.
