I scoured the net to no avail, I couldn't even get a clear understanding
of "Orientalista" or "Juno"
This is the only reference I could find which supports Blair's comments:

My guess is that it is some type of revemue or tax stamp and
hence not listed in Scott.

If you look at Scott 776-786, you will see that the word Orientalista
WAS OVERPRINTED WITH THE WORD POSTAL. This would
imply that the Timbre Orientalista is NOT a postage stamp.

My guess is that it was mandatory/voluntary tax stamp with
the procedes going toward development of the six eastern
provinces of Ecuador (Amazonia).

The population there is only about 620,000 with two-thirds
of those being in the countryside and one-third in the towns.

Naturally the design is not identical, but this would merely
imply an earlier (or later) of revenue / tax stamp. It is too
bad that we cannot see a date on the cancellation.

Back in April, a lot of 41 various charity seals and other
cinderellas (including a 30c timbre orientale) was
offered on ebay for $3.00 US - hence value would be
about 10c.

I hope that this helps you.
