Bully cow - "sonderedition" or not?

Hi! Is this lying cow from Bully (1982) some special edition figure, or has someone just painted it by themselves?

I bought it as a "sonderedition", but the paintwork doesn't really convince me.. I tried to carefully wash it, when the paint started to come off from the bottom of the figure.

Thank you for any help!

Bullyland did make some sondereditions with bright colours, - but I think that one looks a bit home made  

Very cute, though ! She reminds me of the model cows you can/could buy, painted by celebreties...what are they called, now

I dont know but big congrats and welcome back    

Thank you  
Hopefully I have more time to visit the forum now than I've had during the past weeks (or months actually..)
Good to be back!
