There does seem to be some similarity with the Boom work, but the style on this seems pretty distinctive. To me it looks more nationalistic or like a coat of arms or something than cupid-like. Is the face on the wings really frowning, or is that a trick of the light?
To me it doesn't look like a Moser-type oroplastique decoration. The relief areas within the design aren't gilt, and it appears to drawn by hand rather than with a stencil.
I saw something Hungarian yesterday that reminded me a lot of this piece. Not that this is Hungarian, but to me it looks like it has some eastern or Islamic influence. Russian maybe?
