Last year, I shared an article regarding F.A.Heckel. The blog I had it on was destructed and I lost the article. Thanks to a 3 days worth of chit-chat with a weebly staff. I quickly transferred the article (and edited and added more pictures) to my 2016 wordpress site. So here it is, so if any questions on Heckel this should really solve it all. https://thevintagenostalgia.wordpress.com/2016/12/30/f-a-heckel-of-dresden/ Enjoy.
