001-002- During the visit in the museum and in particular in the room of the personal collection of helene Godtschalk and her sister Isabelle 003-004- I have had a strange feeling with one of the sunglasses presented . 005- I looked at the legend and i had found the inventory number to look in the database. 006- When i found the item it had no picture. 007- Then I asked my own personal memory/database and i found this photography where I wear exactly the same sunglasses ! There are exactly even, bought on eBay 5 years ago for 10 euros in a package of old sunglasses. I had noticed what there were heavy and apparently silver. I visited a specialist and he considered what dated napoleonic period. 008-009-010- Then i modified the form in the database with my picture to propose another version of seeing objects in different contexts, maybe in real context, outside of the museum when it's possible... 011-012 And about the outside i made some researches from the tympan we saw in the basement of the museum with emile. The tympan was created by François Rude and it seem to be installed on the stock exchange of bruxelles. 013- So i take some photos of the main tympan in front of the building but it seemed too big to match with the museum's tympan. 014- So i look at the other tympan, behind the bourse and it seem to be in the good proportions. A question still not resolved is when the tympan was recovered, and i can't find the reason (emile said us it's after a fire but no sources on the web (wikipedia FR EN NL) 015-016-017- Then i decide to declare in open street map the existence and the actual emplacement of the tympan 018- Maybe we can propose to the museum to give an acces to this art piece, first by adding an items in the database for the tympan, and maybe in the futur, a public access to the tympan in the basement of the museum.
