I repeat that this short reels were shown usually before movie shows and they lasted around 15 minutes covering at least 4 topics. they were black and white, narrated in spanish.90% of the topics dealt with european stuff.
The last one I saw was in the early 80's. At the beggining of each show there was a globe with the logo UFA. I have
tried to contact ufa with no success but then, I'm not very 
good surfing the net.However, these shorts were really great
and were shot in magnificent black & white and I have to have some. Thanx for your reply. I xpect you to let me now all you know about this, OK MR?
