„ im Internet habe ich in Ihrem Katalog das vorgenannte Werkverzeichnis … gefunden …

Mit Interesse habe ich auch Ihren offenen Brief an die Herausgeber der Frankfurter Allgemeine Zeitung vom 24.7.2003 gelesen, zumal ich (bei früherer Gelegenheit) … mir … von der Frankfurter Allgemeine Zeitung den Vorwurf des ‚Kulturglobalisten‘ gefallen lassen mußte … “

“ Stumbled upon your excellent website while researching Ludwig Beckmann, and must say that I was most impressed. In any case, since you are the closest I know to an authority on antique German books and prints I am wondering if you could help me pinpoint the origin of a piece I have in my dachshund collection … ”

(Mr. & Mrs. J. L., August 14, 2008)

“ … Thank you again for your considered thoughts. I am interested in the ‘Clara’ piece. Please describe the process for completing a transaction for #15,275 ”

„ Beste heer Niemeyer, Hartelijk dank voor de snelle terugboeking (concerning a bill paid for already one year ago). Zoiets schept altijd vertrouwen! Beste groeten “

(Mijnheer P. E., 3. Februar 2009)

„ … Übrigens ist Ihr Internetauftritt wirklich überaus interessant, habe ihn unter Favoriten gespeichert und schaue sicher öfters rein “

(Herr J. F., 27. Mai 2013)

„ Herzlichen Dank für Ihre freundlichen und aufschlussreichen Ausführungen, die mir die Beschreibung des vorliegenden Exemplars sehr erleichtern. Schön wärs natürlich, wenn sich Ihre vielfältigen Kenntnisse zum Werk Ridingers vielleicht als Artikel, oder Artikelserie, im Aus dem Antiquariat oder einer Bibliophilen-Zeitschrift einem breiten interessierten Publikum zur Kenntnis gebracht werden könnten … Ich würde mich jedenfalls sehr darüber freuen, Expertenwissen aus erster Hand zu erhalten. “

(Kollege U. K., 12. Mai 2015)

“ Thanks a lot for your answer to my request, in such a short time and in such a detail! I’m pleasantly surprised with the fact that you presented me 3 different options! The 2 options … although very tempting (pricewise, extra prints etc) do not interest me, because of the condition of the prints. As a collector I wouldn’t like anything else but the best – the first option. To be absolutely honest with you, I expected the price to be high, but not so much … (It’s a) ‘Museum quality’ piece … Congratulations for the excellent pieces you offer !!! ”

(Mr. L. M., January 12, 2016)

“ Arrived March 16. Beautiful, very pleased; impressed with your entire process. Thank you so much. Best regards ”

“ Thank you for your lovely message which I will read at leisure over the Christmas holidays. I am retiring from the … after 32 years of service. I have been so fortunate to work with a fabulous collection, wonderful colleagues and such knowledgeable antiquarian booksellers like you who have made my job challenging, simulating … and such fun … Please accept my best wishes for a merry Christmas and a happy and healthy 2018! Warm regards ”

And how does niemeyer’s react if they think an item may ultimately not come up to the customer’s expectation ?

“ However, the anxiety and insecurity showing from the kind of the continuous flow of questions indicate that you are not feeling comfortable with the whole process. So it would seem to be wiser to call the matter off at this point, as ultimately you may not be truly satisfied. As you will have noticed on our Testimonials page it is – and always has been – the business policy here in such cases rather to wait until we can become friends on an item which stirs up less discussion. In line with this I therefore have cancelled the invoice of … ”
