As of today, you can purchase A4 prints and badges through my Etsy Store. It is open through till May 30th, then it will be closed until August 10th, as I am away on vacation.
At the moment I am not selling A3 prints, these are available in store at All Star Comics in Melbourne. I will be taking private orders for them in August, please send me a message to be placed on a contact list. Also if you have a specific request for a print from my artwork or would like to see something specific on Etsy or Redbubble, please send me a message on my facebook page or send me an email.
