Brussels World's Fair/Expo 1958 Atomium Souvenir Building Silver On Marble Base

Description

Offered is this really cool 1958 Brussels world fair expo paperweight souvenir building of the Atomium. It's made out of silverplate metal on a marble base.
More of an unusual one and that it's silver plate and larger that the pieces I have seen.  Also, much nicer quality.
Has signed hallmarks or foundry marks which i'm not familiar with.  Measures 4" tall by 4" wide and in very good condition. Some small fleabites on the edges of the marble base but displays really well.
The Atomium was built as the main pavilion and icon of the 1958 World Expo of Brussels (Expo 58). In the 1950s, faith in scientific progress was great, and a structure depicting atoms was chosen to embody this. The Atomium's nine 18-metre-diameter (59 ft) stainless steel clad spheres depict nine iron atoms in the shape of the body-centred cubic unit cell that could for example represent α-iron (ferrite) crystal, magnified 165 billion times. It is located on the Heysel Plateau in Laeken, where the exhibition took place. It is now a museum.
Designed by the engineer André Waterkeyn and architects André and Jean Polak,[1] it stands 102 metres (335 ft) tall. Its nine 18-metre-diameter (59 ft) stainless steel clad spheres are connected in the shape of a unit cell that could represent an iron crystal magnified 165 billion times. Tubes connecting the spheres enclose stairs, escalators and an elevator (in the central, vertical tube) to allow access to the five habitable spheres, which contain exhibit halls and other public spaces. The top sphere includes a restaurant which has a panoramic view of Brussels. The building was completely renovated between 2004 and 2006 by the companies Jacques Delens and BESIX.
