I post here a picture of a London Olympic Committee label strip in brownish orange colour. I think it is a colour trial as it has no gum and I have seen picture of a perforated Olympic Committee label which is brown.
Does anyone have more information, for example who printed these labels or who would have made the rather attractive Britannia design? I think these are another example of how much more pleasing cinderella designs are in comparison to stamps.
Perhaps they had to try harder because these labels had no value in paying revenue and the only way to sell them to get money for a good cause was to make them look nice.
