No comment really needed, and in fact, I'm sure my mother wouldn't approve if there were any. Hi mom!
UPDATE: I received this pic from a reader, and I am not certain it was ever used by Pfizer. I have heard from the designer of the item, Einav Jacubovich, and he has asked for attribution. Clever idea at least, but possibly not a real drug rep toy.
UPDATE 2: I have confirmed this was never used as a pharmaceutical advertisement. Clever idea though.
