If you need any of this stuff we have a bit left over from this morning, yesterday, Friday, the day before that etc. etc.

Edit:
As anyone who follows my journal knows I'm never satisfied with my work but I just realised this is the anniversary of "THE PHOTOGRAPH".

Out of 1185 blips I have two that I'm really pleased with and the one year ago today was one of them....
