This was once sold at Sotheby's Auction house -- so I think it could be legit. Current seller has all authentic items on his page.
Price is very high though and hard to find one's to compare (as did they ever sign children's drawings before?)
there fine in my opinion
I get concerned when the autographs are the same color as the paper. It makes me wonder if the piece is original or a copy.
Agreed. On one hand they look like ink, but the color suggests pencil as the drawing, but then some appear faded which pencil does not...
