The Flagrant Cabbage details were revealed in the A4 proof sheet of 4 giant sized stamps made available to collectors. This large size stamp first appeared in the presentation sheet detailed earlier, but there were other plans afoot for this large print. Discussions were held around creating the World’s largest stamp and naturally Bloody Stupid Johnson was mooted as a subject. To hold such a record it was thought to need to be perforated and in a sheet, but could valid for postage be extended to Discworld for Guinness Book purposes. Anyway the Cabbage Fields evolved from this.
The A4 sheets hold 4 stamps slightly under A6 size with a vertical gutter holding the sheet information. This was repeated in the right margin. When available on the shop website however this sheet information was included with the stamp on the illustration. Basically it was as if the right hand perforations were missing. However was this a faulty mock-up? The real life stamps were perforated on the Wincanton perforator, while the illustration shows them much more realistically perforated for their size; perhaps perfed 3.5. This suggests use of Photoshop for the website illustrations.

Colin Edwards also thought the standard Wincanton perforations did not suit such a large stamp and printed some sized 120x93mm which received larger coarser perforations - approx 7.5/cm. Some of these were used as labels on post, while unused examples were sent to a few collectors during 2011.

It was said : There was at one time a request for a very big stamp to completely dwarf the envelope it was intended for - which devolved into the big Cabbage Field stamp in the end. Hilary (Daniels) was determined we should have the record for the largest postage stamps ever produced - but I pointed out that rather than just designing the biggest stamp we could, we should first find out what the criteria was for a postage stamp and as that meant it would have had to be approved for postage purposes then it all fell down. Nothing to stop them doing a stamp intended for postage in Ankh-Morpork and winging it with the Guinness records people though - but we got steered away onto other things.  I think the only other criteria was that it had to be perforated and produced on a sheet - but not how big the sheet needed to be or even whether the perforation could be applied by hand - all do-able in my opinion and would have got us into the philately magazines too,
