I guess I have one SPARTACUS left in my ebay-shop (Juniormike is my eBay name).
Without too much patriotism I always thought that German paper was hanging around at
the top for many decades (not all titles of course). My #1 was always Italia, not all titles either of course.
I also love certain Quads, Japan & Belgium of course. Spain & Thailand. Some French. Some 1-sheet's (but most
have way too much text and white space on them, for my taste anyway).
But I think when it comes to lobby cards Germany was really #1 in the 50s / 60s. Huge wonderful
sets up to 30, 40, 50 cards! And no cheap prints either, they were expensive to produce. After
the war cinema was huge here and distributors had the money to pay their poster artists and to
produce those glossy lc-sets (photographic photo stock, hand-tinted, sealed...)
