A remarkable 153 stamps were released in 2015 and The philatelic Bulletin would like to find out which we preferred. Each issue is illustrated here and you can vote either by filling in a copy of the form that appears on the 3rd page or just putting your preferences in an email to bpb. firstname.lastname@example.org. The prize is a 2015 Royal Mail Year Book.
I suspect that Star Wars will sweep the board for sets. The individual winner is less certain. My vote is for the #59 First World War commemorative stamp. Amongst the sets, I will vote for the Machins, of course, but actually think the Bridges and Christmas issues were very well designed. Individually, the #35 Humber Bridge may do well.
I rather think that one of the Smilers, #11 especially, may come bottom of the poll, with the £1.47 Inventive Britain not exactly likely to garner many votes either.
