It's an odd phrase, given the background to the religious story, but so few people actually practice their religion these days that secular considerations of eggs, rabbits and cards seem to have taken over - I couldn't even find a religious postcard for my previous greeting (see below).
Thanks to MG for sending this from Glasgow MC. I understand that the other machines have the slogan in three lines.
I wonder if Royal Mail will take up the suggestion to have a slogan for National Stamp Day/Week? One can only hope!
UPDATE 13 APRIL
The Valentines Day postmark does make it into the April list as Southampton were still using it on 3rd, 4th and 5th April! Thanks to RS for sending these pictures:
But then they switched to Easter - I wonder what will come when that campaign finishes?
UPDATE 21 APRIL
It looks as if North West Midlands is taking a leaf from Southampton's calendar as this arrived this morning - Happy Easter, used 19 April
Edinburgh Mail Centre was also using Happy Easter on 18 April but the copy I have is on a Post and Go stamp (one not from a collector!) and so doesn't really scan well.
UPDATE 26 APRIL
It's National Stationery Week and so there is a new slogan to encourage people to write! This one from North and West Yorkshire on 25 April 2017.
Thanks to Mike for sending this version of the Stationery Week slogan, reversed, from Tyneside MC on 24-04-2017
While we're on postmarks and variants of them we don't usually see the older machines other than at Christmas, but Carlisle has dusted off this one out of the back room for use over Easter. Cumbria, Dumfries & Galloway14 APR 2017
