Scott,

first of all I have to correct myself, the campaign " Gruen - The Newest Look in Time" itself was started 2 years earlier already, prepared already in August for that year's Xmas season. Each year there was a new bunch of models for this campaign. What I meant is that the Eldorado together with some other models were added for the 1957 campaign.
Unfortunately I am right now totally overworked and this state may last until Christmas (hopefully not longer). Until then I fear that I would not be able to afford the hours which are necessary to scan through my archives and get you all I have on the Eldorado. Please post or send me a reminder by PM should I forget about this inquiry during the coming weeks.

Barney
