Hi.
Stationery/stationary... That reminds me of an old joke in which
a bussinesman while checking in to a hotel asked the cute young receptionist if she kept stationery. To which the receptionist replied:" Yes I do sir, 'till someone touches my ****, then I go all wild.
What is more surprising about the CL ad is that David Lee Roth actually was able to write in 86'

.
Therefore I'd say it's a fake.
