Rare example of full sheet of the 2005 Classic ITV Smilers sheet as issued by Royal Mail (1st x 20 face value) with blank labels attached to the stamps. 

Normally these can only be obtained with personalised images printed on the blank labels but this sheet has found its way onto the philatelic market with completely blank labels!!   These are very much rarer than the personalised versions of these sheets which in turn are far more difficult to find than the generic issues from Royal Mail.
