Post dating pictures before death of the artist

[Segilla]

Ive an oil paintung on white opaline glass with a clear date, 1896. I've identified the artist , with very, very little doubt that he is not he man who painted it. However, the date is a year after he died..Is this a known practise?

It's possible that what you have is a Crystoleum, a method of making a print or lithograph appear to be an oil painting,by attaching to glass.
See here:~http://www.arthaul.com/2009/victorian-c
rystoleums-how-they-were-made/

If it is that would account for the date after the artists death.
Some examples here:~

Hopefully this link will work,as the one above didn't.

Thanks Mr Veritas. Very intersting and completely new to me. My painting is definitely oil as the medium can be felt.
The article didn't make it clear why flat glass was unsuitable for chrystoleums.
And as frequently told by my woodwork master (1844-51), apart from during WWI, "There is no such thing as sandpaper as it is made using ground glass"!
