Souvenir Bold  Vorgeschlagen von jerseygirl 
Audebaud  Vorgeschlagen von skac83 

It is quite strange that the logo of this company cannot be found on the Internet, especially in high resolution, even though I have already searched everything. Does anyone know this font?

I think there are two different typefaces in your image. Notice the two different 'L's?

'B' could be Souvenir, just a guess, though. The rest reminds me of Clarendon, but it's
not that good a match either.

Sorry, I tried

Hmmm, I think I found something. And how about the Audebaud font? What do you think?

Much too rounded. You'd do better with Clarendon.
