From 1922 until 1948, the country we know as Isreal was governed by Great Britain and was known as the Palestine Mandate.
Initially Egyptian Expeditionary Forces stamps were overprinted for use; but in 1927, the only set of stamps for this area was issued. Four designs were used for the set.
Identifying the 1927 Pictorial issues (Scott 63-84, or Gibbons 90-111) is a matter of differentiating between four different paper types, and sorting the colors and some perforation varieties for a few issues. All of the stamps were issued on paper watermarked Multiple Script CA, so you don't have to identify the watermarks to sort these stamps.
The primary factor that makes identifying the Pictorial set so interesting is the four paper types that were used in printing the stamps. They are very distinctive and can be easily identified and sorted. They are listed below:
1. Thin paper - used for the initial 1927 printings.
2. Thick paper with Vertical Ribbing - used for printings beginning in 1928 thru 1932.
3. Thick paper with Horizontal Ribbing - used for 1937 printings.
4. Wove, white paper - used for printings beginning in 1936 until the end of the Mandate.
The paper types are not listed by Scott, and are barely covered by Gibbons; so if you want to specialize in this set you will need the catalogue published by Michael Bale.
My reference collection is shown with scans including blow-ups of the paper types and examples of the various shades. I am still missing a few, so please feel free to contact me if you have any of my missing items. Use this link to view the site.http://www.kgvistamps.com/articles/...te-1927.html
