Paris 1951: Three Photographs

I've taken a closer look at the three photos that came in the envelope with the postcards and business cards.

All of the photos are black and white, printed on the standard glossy-front matte-back commercial photo development stock with scalloped edges, lighter but similar to the postcards.

One is of the Eiffel Tower taken from the Trocadero, the standard tourist shot except there are no people on the plaza and only three way off in the distance.

The other two, which I originally believed to be aerial shots, were, in fact, taken from the very summit of the tower itself. One is centered on the Arc de Triomphe, and the other is centered on Le Grand Palais with Sacre Coeur on the horizon. The back of the last one has "Eglise Sacre Coeur" handwritten in pen. The back of the Arc de Triomphe shot simply says "arch" in the same hand, and the one of the tower is blank.

I presume there was a whole roll (at least) taken in and around the city but these are the only ones in the envelope and there are no negatives to be found.

None of these additional landmarks are included in the postcard "tour" although La Madeleine is distinctly visible beyond Le Grand Palais and both Place Vendome and La Bourse (positively) and L'Arc du Carroussel (possibly) are within the span of the image if not discernible.

Hmmm. I just noticed that this last photo also encompasses the neighborhoods from the two business cards which, from this perspective, would be just below Montmartre and Sacre Coeur.

So, is it simple tourism that ties these all together? The handwriting on the photos and the business cards is different. I don't know who "Georges" is nor "M. Presse" (both from the business cards). And who was staying at the now defunct Hotel Metropole?
