I reported it to ebay also Heather.
I understand how you must be feeling, not so long ago I found someone selling paintings supposed to be done by me....no way did I do them, I've thrown better in the bin many a time!!!! These paintings that where being advertised as my work not only used my name but also the Riders for Health charity auction on Day of Champions as reference to my paintings.....After I reported them as being fraudulent I've not spotted any further paintings that I'm supposed to have painted, thank goodness!!
For you though it must be so annoying to have this person making money from your talented artwork.....some people simply have no scruples do they!!!
BTW...it's a very good graphic Joss.....congratulations on doing it, it's truly smashing work. Well done YOU!!!!
