I have no clue why some of the Jumbos in some of my photographs look white. While others are darkly colored... This image is a good example. Perhaps they were made of a light-colored composite material...or porcelain? Of maybe they were painted for some odd reason? All appear to have been mounted on large, stocky pins like the Jumbos were. Click "Next" for a close look at the top of this trolley service pole.
