I suppose, in theory, we could be considering a company formed between 1945 and 2006, ...
and
... They might have this one, but that would be a first in over 10 searches I tried of unknown labels, signs and marks. No use paying for access to something so incomplete.
I had another look at their web page, and their (partially difficult to read) instructions. Apart from guests they have three categories of users:
Registered users (free of charge) get a little extra info. So I can now tell that the logo was taken from a label of around 1967 - which doesn't tell us anything about the time of foundation of the company, of course.
Quota users (€ 10) will also get the name of the company - for up to 20 marks within a year: only if you actually request the info for a mark you have found, 1 search will be deducted from the quota. In other words, if you find 20 marks within one year, and request the related info, you pay 50 cents per mark ... becomes more expensive if the quota is not used up.
Premium users (€ 66 per year) get unlimited access with additional info, e.g. links to all other marks used by any given company. This will only be of interest for the "professional", I guess.
Just a thought - based on another topic I'm interested in - genealogy: several Swiss church records are available on CD, which are quite expensive, far too expensive for the occasional limited search. Several researchers have bought these CDs for parishes where they research a lot - and offer lookups (free of charge). Is there anyone on GMB, who already is a quota (or premium) user - or would become a quota user, to offer something similar? Whoever is interested in using this offer, would have to search for the mark himself (as this is the time consuming part) and submit the URL where the mark was found - so offering this service would only be a few mouse clicks (plus the € 10, of course). Refunding such small amounts of money is not worth the effort - so users of the church record lookup are invited to donate a small amount to a good cause.
Whilst helping collectors, this would also be advertising for the web page - as some collectors, after seeing a few examples of their info (without paying) may then decide to become paying users themselves.
What do GMB members feel? Will 20 marks per year found from the 15'000 marks (of 11'000 artists or companies), to make this worthwhile?
