I used http://www.random.org/ to generate two numbers:
Which generated 50 and 73. Compared to the list of 100 likes on Facebook that means that the lucky people receiving a free print each are *Drum roll*
Celia Daniels and Hannah Gordon-Smith! Congratulations. I will be in contact with them shortly to arrange the free prints.
Next prize round will be at 250 likes, so get spreading the word and good luck!
Thanks for following me.
