Question about an old painting! Would anybody know where to get a poster?

1841 ,Benjamin Heinrich Orth  "Waffelbaeckerin"

This is an old painting by a german painter from Mainz. His paintings are in the Landesmuseum of Mainz, but i can't find out if this one is or where one could get a poster of it....If anyone would know, or have any suggestion about it...very wellcome! 

My second son, who signed in as follower on his mum's blog, loves waffles ever so much and we have been searching for more on this painting for a long time. It was presented on the German tv show  "Kunst&Krempel" (art and staff) some years ago. In this show people can bring their old "treasures" or findings and have them estimated. My sisters and me had been there to have 2 old porcelain figures estimated which were from our grandfather! 

The above painting is considered very rare and quite worthy because of the theme! Well...i am just looking for a poster of it! (Would be a nice present for my son...it's his birthday today!)
