Small book gems

I managed to contain myself and put most of the books back I had picked up.
I walked away with just two!
One of the books is a guide to the South Kensington Museum. It is a catalog printed in 1897 and sold in the museum in that same and the following year.
It is in pristine condition and lardered with funny ads, nice crisp ground floor plans of the Science and Art museums. A true gem at only 3€.

And then another surprise as I unearthed a catalogue of the Salon d'Anvers of 1855. I worked on the Salon on 1843, I bought this as a little memento. It feels like I stole it from the archive and now treasure it like some art thief who steals for pleasure.
A stamp on the inside does tell me it once belonged to the collection of the Antwerp city library. I should wrap it in some protective paper, the back is half torn and it is an annoted page. This rare thing set me back just 10€, so I stayed below the 20€ threshold I had agreed with myself.
And I managed to save on a train fare this morning, as the conductor failed to show up. So I have permitted myself to spend an extra 3,90 + 7€, if I have some more time to spend idle amongst volumes of knowlegde.
