Ok, I picked away at them and here's what I found. Although the sides are pretty much fused together, more so than the cello on a standard Bike deck, the both appear to open towards the back. In other words, if you look at the front, it seems like the strip would peel away from you. Both strips start on the left side. Another interesting thing is that then"red seal" deck has a MUCH heavier embossing on the tuck. It's most apparent in the leaves on the back. Check this relatively flat pic...the leaves are "domed/curved/embossed" much more. It's night and day in real life, far more so than even this pic indicates.
Also, the "banner" area on the front containing the Monarchs name, is deeply set on the "red seal" deck, and pretty much flat in the deck without the seal. So the "red seal" deck is deeply embossed, that the "no seal" deck is embossed, but you have to rub a finger across it to know that it isn't flat. Very interesting!
BTW...the "red seal" deck is in the right in both photos.
