The first
Mickey Mouse Annual, published by London's Dean & Son Ltd, is of great significance in the history of Disney publications. Published possibly around Christmas of 1930, it is the first-ever Disney book published for retail, a
Mickey Mouse Book which had come earlier in the same year in the US having been printed as a give-away for promotion purposes. Furthermore, this
MMA marks the first-ever appearance of Disney comics produced for publication other than newspaper syndication.
The annual opens with the below color plate...

...opposite this title page:

Oddly, there is no reference whatsoever to any affliation to the Disney company in either this title page or anywhere else in the annual that I could spot (most subsequent British Disney publications would include a tagline about "permission from the Walt Disney Mickey Mouse Ltd.").
While the larger figure of Mickey is copied from a US cartoon poster, the small Minnie figures at the bottom of the title page are taken from a model sheet produced by Disney to be utilized in creation of graphics on misc. items. See post dated March 30, 2009 from
http://vintagedisneymemorabilia.blogspot.com/ for some info on this sheet as well as further examples of its utilization in
MMA, including the figures in the below introduction page:

Below is the scan of the first gag page (acc. to David Gerstein's index at inducks, it is "partly made up of US clip art").
This is in a format close the comics format in the sense it includes more than one 'panel', but, in my opinion, would qualify only as a 'pseudo-comics' because while the the panels are sequential in a sense, they are not in the same diegesis (ie. the event depicted in the second panel is not of the same plane of reality as of the first panel).
The subsequent page on the other had features the first gag in the 'proper' comics format:

The artist on this, and most of the other comics pages in
MMA, is Wilfred Haughton, best known as the artist of the highly acclaimed cover illustrations of Britain's
Mickey Mouse Weekly onwards from its inception in 1936 till circa 1940. Haughton had been working on Dean's MM Annuals prior to his assignment to the
MMW project. The bulk of the first
MMA consists of such gag-a-page comics. Below follows a sampling of my favorite ones or those which I find interesting for various reasons:


I find the above gag noteworthy for two reasons. First, the side-line inclusion of a secondary humour element in the monkey silently stealing Mickey's food in the second panel is remarkable. Furthermore, producing a gag about women's fear of mice personified in Minnie's such fear is, on one had, ironic since she is, after all, an andromorphized mouse, and, on the other had, significant in showing the degree of internalizing the andromorph nature of Minnie (and Mickey).
The below gag is interesting in its inclusion of proper human beings into Mickey's world, which is out of line with Disney comics in general:
For my taste, I personally find the two below gags some of the funniest in this annual:


Unfortunately,
MMA also includes some rather distasteful gags as well:
Even if the majority of the gag-comics in the first MMA can be assumed to be the work of Haughton, there were clearly more than one artist working on the comics in this publication. Below is a sample with markedly different and far more cruder graphic style:
In addition to gag-a-page comics, the first
MMA also includes several gags in the format of non-panelized illustrations accompanied with text. The below one is interesting because it features Minnie's "papa", which we never see or even hear about in US comics:

Several of these non-comics gag pages incorporate illustrations from the US
Mickey Mouse Book, such as the below one (see the post on
MMB from Nov. 22, 2008 on this blog for a comparison with its original US edition):
The first MMA ends with this advertisement:

However, in addition to the first one at the very beginning, there are three more color plates throughout the annual:
