After the insults (in another thread) I was going to just walk away from this thread and wash my hands of it. However, I have been prevailed upon by another list member to set the record straight. So here goes:
In the OP pictures above of two stamps identified as being on "pelure paper", the paper is demonstrated for being a hard paper with high translucency. However, it is not clear that they have the "transparency
" which is characteristic of actual pelure paper. I propose a test along the lines of the following:
Let us start with the pelure paper Bowlsby essay shown by essayproof. Something of the texture of the paper is shown by that pic, but it's translucency is not easily seen there, let alone its transparency..
Here is another pair of that essay which I have placed upon a printed card to show the degree of transparency.
The design beneath the essay is complete top to bottom and visible the whole way. The paper was treated with a sizing agent that gave it that kind of transparency. This is a pelure paper of the 1860s.
In the mid-1870s another pelure paper was used by the Philadelphia Bank Note Company in preparing some models in their bid for the contract of 1877. Here are a couple of examples side-by-side on an exhibit page:
These two are of different printed colors but are on the same type of pelure paper. The example on the right has a pencil inscription beneath it which is visible through the paper. This stamp was purchased from Bill Langs on eBay, and its ID number is given. You should be able to make out when it was purchased and the price paid. (I had not anticipated this much transparency when I mounted up the page.) The example on the left had no such inscription.
Here is another example from the same exhibit page, this time in a color shade similar to that of the three cent Continental shown by the OP, albeit with less yellow tint.
This too has an inscription beneath it which can be read through the paper.
Let me suggest that the OP write something on a small piece of paper, slip it beneath one of the "pelure paper" samples on the album page as above so that part of the inscription is beneath the stamp and part is left uncovered. In this way we can assess the degree to which this paper sample shows not only the translucency but the characteristic transparency of true pelure paper. Your best bet is to position your lettering below the numeral "3" and the wording nearby.
