File talk:Louis Pasteur by M.P. Nadar.jpg

Louis Pasteur image source

The image I scanned was not from a book but a single piece of paper. I found this when I looked in the old postcard boxes in a bookshop in Brussels. I often spend some hours mining the miscelanious pile of postcards and other pictures to find something usefull to upload. There where 3 exactly the same pictures in the box. I bougth on of them. There is a clue to the publishing house. On the left side there is the mention: Hélio Aulard, Paris On internet I can find some works of this publishing house: https://www.the-saleroom.com/en-gb/auction-catalogues/auction-team-breker/catalogue-id-breker10009/lot-7f289e18-9c28-412b-8e33-a6760171bc3f and https://www.abebooks.co.uk/Nus-Acad%C3%A9miques-Nature-na-Helio-Aulard/1289466138/bd I suspect it is fr:Alphonse Aulard a known French historian/publisher who probably reprinted the picture of Louis Pasteur as a collectible for a scrapbook. But this is speculation. Shall I put as source: Publication of Hélio Aulard, Paris?Smiley.toerist (talk) 22:59, 2 August 2018 (UTC)

i do sympathise. but you realize how bad the scholarship is: "i found it at a boot sale"? you should have a place where scholars can find the item, or it is not verifiable. you realize how many newbies get their scans deleted, when they say "scan from book"? they just deleted Madela's diary with more verification. we have multiple prints with multiple provenances. you are now speculating on the book source. why don't you state facts about this item in the description / object history (in photograph template) the reprint publisher matters less than the origin of the photographic print.

You clearly mis the whole discussion on Commons:Village pump#Wich Nadar fotografer? where the conclusion is that several of the same images come from the same photografic plate sometime around 1890. The photografer and original source is not in doubt and is PD. [1] By the way: A lot of old images come from postcards and not from academic works. Wich publisher reprinted the image is not really relevant for the licence, (he only added the name and 1822 - 1895) but even there I found it: Hélio Aulard, Paris. Most of other images in Category:Photographs of Louis Pasteur by Nadar are scanned bij historic collections (libraries etc), but private scans of original printed material (postcards etc) are as valuable as official ones.Smiley.toerist (talk) 07:39, 3 August 2018 (UTC)
