BicicletaFavor - the 3 pics that
machinist42 and
juvela posted so far are the only three images I'm seeing in your 2 albums.
One of the album cover images (the one on the right) is a thumbnail of a bike with somewhat unconventional design, but the full size picture doesn't seem to be in either album:
Anyways, the close up of the fork crown shows a panto of a Spanish marque called
Massi.
The panto is the outline of the full logo:
Hard to tell, without more pics of the entire frame, whether the frame is a Massi as well. If that fork is attached to the frame in the album thumbnail on the right, then I'd say the frame is something else. I've never seen a Massi with such unusual geometry/construction.
Mecacyle was a company that produced something like 500-600 frames a month and most of those were wearing decals of shops all over France (and other countries). Their
Turbo model (one with a split seat tube) was the most popular and, consequently, most commonly found nowadays. The carbon ones are a pretty rare sight. There was a post about
one on a French bicycle forum and it looks like it was constructed of chromed Vitus 980 and carbon tubes:
As for the other bikes in the picture, the De Rosa looks a little suspect and the middle one looks like a 1950s or posibly 1940s
Alcyon. That head badge, along with the box lining and the fillet brazed construction would all be consistent with Alcyon.
