New Massad labels

Last week (12/12) there was a new Massad printing for the 21st Philately day. What is interesting about this issue is that it appears that 2 different sheets were issued. They are both tete-beche sheets of 10. The difference is one sheet has only the 1.55 value, while the other has 10 different values. I don't believe either sheet is available through the philatelic services standing order service. I have seen both sheets available on E-bay in both Mint and FDC, at close to face value.
