These are absolutely stunning, and such great scans too, thank you. If I may ask how do you source all the images for your blog? Do you own all these books yourself? I'm curious because you post some pretty rare things like Lefler's work that I've never been able to find anywhere else online this completely and in such good image quality.
I find rare books and images at online-auctions (Ebay, Bonhams, liveauctioneers) and online-libraries. I edit the color and contrast, removes artifacts and only then spread to the blog. Sorry for the bad english. I use Google translator.
Thank you thank you thank you!!! Your blog is a beautiful archive of amazing books i would otherwise never seen!!! What treasures you be-trove us!
