I've wanted to quote this for many years.
Winston Fletcher used this with images at an Advertising Association presentation at the CBI in October 1984.
When the client moans and sighs
Make his logo twice the size
If the client still proves refractory
Show a picture of the factory
Only in the gravest cases
Should you show the clients' faces
Found in 'Welcome to Optimism' after several false starts finding the right search terms for Google.
This is another way to look at it:
I was a trainee Rep at JWT.
My merry dance around the world of advertising continues with occasional afternoons mentoring at the School of Communication Arts which I attended in 1987.
I kept a daily diary at the time, most days a single sheet of A4 whether I felt like it or not.
This was Tuesday 9th October 1984.
It was a fortnightly or weekly IPA meeting that attracted graduate account managers from across the London advertising agencies. The diary entry reminds me who I was with, the ads we looked at, where I was and what I got up to. Plenty in fact to bring it all back in considerable detail.
The other quote or image I am looking for was a set of dimming light bulbs to illustrate the 'Mortality of ideas' something that threatens and crushes many a great project.
