Looks like a mostly unskilled person made it in pottery class about 5 years ago.
I think I could do much better.
I'm not a pig expert so my opinion is pretty worthless.
Maybe its worth $1,000,000 but I wouldn't give $5.
Thats the 2nd one I've seen on ebay recently. Looks like something my daughter made in 5th grade art class. Poor quality repro made to fool people into thinking it is a valuable Anna Pottery pig worth 10K
