I must excuse me ... but i really don't know what was going on there in 1990. I went by car for Hours from Lisboa to O Porto, arrived in the afternoon - and tried to get some nice Photos at the Banks of the Duoro. So i took this Photo and followed the Tram Line to get some other Motives. I didn't see this archaic Vehicle again ...
From a hint of "Bee" (NKP 765), colorful "Bees" (KCS), "Bees" w/ "attitude", to "Bees" that "sting" your eyes, in their own way they have "Bee" on display! Equipment that "Buzzes" with Yellow & Black colors! ("Bees" can still "Bee" entering this "hive"!)
