The Stamps of the Faith Press albums have evolved over the years, design wise, but for the most part have always been 51mm tall and 30mm wide. The exceptions to this have been the earliest albums where a 38mm tall and 28 mm wide stamps was used, while a 37 by 27mm set is part of the collection but is is represented by blocks of stamps and not associated with with an album. For the later stamps though, while a number of styles have been issued, these have been used across album titles, and different sets/styles were n used concurrently. Thus albums of the same title and same year may have completely different sets of stamps inside. Whether this is because there was a choice (perhaps different churches had different tastes or requirements), whether the stamps sent out were randomly distributed to different Sunday Schools, or whether the schools used old stocks some years is unknown.

This is an attempt to try and classify the stamps used for the regular Sunday attendances, to identify variations on a type, and to list which years these stamps were in use. I do not know the exact size or arrangement of stamps on sheets, but an indication is provided by some strips and blocks of stamps stuck onto loose pages.

Type I

The stamps are single colour, though different colours (green, purple, yellowish) are used for different periods within the church year. The actual Sunday is at the bottom and there is some additional text.
These were in use up to at least 1912

Childermote 1908-09 Childermote 1909-10 Childermote 1910-11 Eldermote 1910-11 Eldermote 1911-12

Type II

 The stamps are the regular Faith Press size, and have a full colour image. The stamps are not specific for a particular Sunday, but have a small piece of text against a coloured background in the lower half of the stamp. The positioning of this is variable, and the background colour varies according the the different periods within the church year.
These stamps were printed so that the same stamp ran in vertical columns while different designs, for successive Sundays ran horizontally.
Type IIa differs in having a proper border.*

The earliest example seen was in an Eldermote album from 1914-15 and also occurs with

Type III

These are two colour stamps. The border colour reflections the different periods of the church year, and incorporates the Sunday for its use at the top, with a quote at the bottom. The central illustration is in shades of grey or brown. The type IIIa abandons the background colour for the text giving a more spartan look to the stamps.

Type IV

 The type IV stamps are single colour, reflecting the church year. Each stamp is specific for a particular Sunday, indicated at the bottom of the stamp.

Type V

These are two coloured stamps. The prominent border has one colour reflecting the different periods, while the image is in a contrasting colour. The border contains the Sunday for which the stamp’s use is intended at the bottom, while the rest has a biblical text.
Some of these stamps are part of the blocks stuck to loose sheets and in each case the blocks consist of identical stamps. This suggests that sheetlets of stamps were printed, one for each Sunday.
The type Va stamps form a set with typical type V stamps*

Sunday Stamps 1938-39

Type VII

A full colour pictorial stamp with a title below, and a more elaborate framing design

Sunday Stamps 1936-37

Type VIII

These are a hybrid of types V and VI. The are two colour, using a frame with the Sunday at the top and title text below.

Sunday Stamps 1939-40
Sunday Stamps 1941-42

Type IX

A more simplified design and artwork. The frame/border is plain and coloured according to the time of year. The Sunday is indicated at the top and simple title text at the bottom. These seem to be the default post-war design type.

Specials

These stamps were used year after year with the same designs, and had a silver metallic finish over the blue. They were more important dates of the calendar such as Easter Day and Whit Sunday, as well as for the Never absent, Never late stamps (when the were awarded). They would appear to have been printed in sheets of one design.
