Sam Taylor-Wood print available at 20x200

Jonathan is a new limited edition print by Sam Taylor Wood. It is available at several sizes and prices, the edition of 100 at 10"x8" looks pretty good value at $60 this size is nearly sold out, so move fast! You can buy it here.

I'm slightly put off by 20x200 only coming with a signed certificate of authenticity rather than the print itself being signed and numbered, this seems fine for the small prints, but a 20"x16" in an edition of 50 for $600? or the 40"x30" in an edition of 10 for $3000? These don't seem very good value compared to her editions from White Cube and Counter...
