I see that Harry Waterson sent you an article regarding 19th Century Exposition Medal Collection in the October 7th E-Sylum. I too have a similar sign in mypersonal collection and I have a majority of the medals depicted.

I acquired the sign from a Heritage Auction years ago and of course the auction house had limited information regarding the sign, the owner or how they obtained the piece. Onecan only assume (I dislike using that term) it was a display of the medals and ornaments manufactured at the address in Paris.

Sorry to say doing my own due diligence I came up with "ditto"

Fantastic 'Le Médaillier' (Paris, France) Medal-Order Shield 24 Medals, Four Military Orders, and Three Coats of Arms in One Display

Fantastic "Le Médaillier" (Paris, France) Badge, Medal-Order Shield. A phenomenal, fantastic, and attention-getting sales sample display from "LeMédaillier" company, Paris, who were based at 13, rue du Conservatoire at the time this piece was produced. This large, wood-framed, plexiglass-enclosed displaycomprises 24 medals of varying sizes and metals; four military orders or decorations; and three coats of arms. In the couple of days that this display was visible in the presentcataloger's office, numerous employees have expressed interest in bidding on it, even those who normally have no interest in medals, military orders, or other exonumia.

Another exciting aspect of this merchant display is the sheer range of work that it covers, from 1823 to 1900. The three coats of arms depict a sailing ship (Norway?), apossibly French fleur de lis design, and a definitely Russian two-headed dragon.

The military orders comprise a beautiful inlaid piece with legend "A la lealtad acrisolada," (perhaps from Spaniards in Cuba), and a second porcelain piece withlegend "Virtuti et merito" the motto of the Order of Charles III. Two smaller orders read "Napoleon Empereur des Francais" and "Republique Français1870."

Medals comprise: Paris 1823, copper, 53 mm, Louis XVIII of France; Paris 1827, copper, 53 mm, Charles X Roi de France; Paris 1834, copper, 53 mm, Louis Philippe I; Paris 1839,copper, 53 mm, Exposition des Produits de l'Industrie, unawarded medal; Paris 1844, white metal, 53 mm "Aux Arts Utiles"; Paris 1849, white metal, 53 mm, RepubliqueFrançaise; Paris 1855, white metal, 53 mm, Napoleon III; London (Londres) 1862, copper, 73 mm, a fine, high-relief portrait of a seated Britannia figure, lion lying at her feet,with three maidens presenting her with gifts from industry and agriculture, three other maidens behind her, no legends; Portugal (Porto) 1865, Exposiçao International Porto 1865;Paris 1867, gilt, 48 mm, Napoleon III; Vienna (Vienne) 1873, gilt, 66 mm, Franz Joseph I Kaiser von Oesterreich Koenig von Boehmen etc. Apost.

Besides its status as an attractive and memorable display of medallic art, this piece is loaded with political and mercantile history. Beginning with the French royalty, thefirm over time created new markets, first with the royalty among its European neighbors, moving over the decades into more and more international markets, participating in thebooming expositions and fairs markets, and eventually reaching faraway customers in countries such as Australia. Although this is a snapshot, a moment in time, of this Frenchcompany, it could become the basis for extensive research into this fascinating area. (NGC ID# 2TGG, PCGS# 661340)
