Commemoration stone, National Amalgamated Approved Society

(Apologies for the distracting shadow.)
The National Amalgamated Approved Society, 30 Euston Square, a joint venture by a number of assurance societies, was founded in 1912 and ceased to exist in 1948.

This is the large buiding on the corner of Euston Rd and Melton St. I'm not sure what it's used for now, probably offices of some sort. Rather ugly, imo, although it does have some interesting details.
