Some more examples of this forgotten printmaker also known from his portraits. He was married to graphic artist Magdalena Ehrlich Matern, who had been student under Franz Hein. 

The blue tit print is stylishly very reminding of Martin Erich Philipp. 

The only known example (to me) of an etching by his wife Magdalena Ehrlich-Matern

It shows a picturesque village square and is numbered from an edition 85/150.
