The Mufti and Pictorial issue of 1938-1942 contains many paper, shade and gum variations that are not explicitly listed in Unitrade. In describing the paper and gum types I have attempted to be as clear as possible in describing all visible aspects. My two blog posts on this issue describe these in more detail, and a third post delves into the complexity of the dotted cover booklets, which began with this issue. In addition to these differences and those discussed in my blog posts, there is also a new perforation difference currently being researched my Mr. Julian Goldberg, as it relates to the coil stamps. Most of the coils of this issue were perforated by a rotary bar method, which results in perforations that are perfectly aligned on vertical sides (i.e. right across from one another). However, there are some singles that show perforations out of alignment, which is suggestive of a rotary wheel perforation. However, strips have also been found, one of which is offered in this sale, where alternating columns of vertical perforations align with one another, but not whth the intervening columns. Research is ongoing as to the nature and significance of these differences. However, in this sale we have made reference to this when describing the coil stamps. Finally, there have been some new re-entries found on the 6c airmail stamp, and three minor type differences found on the $1 Chateau de Ramezay, which are illustrated in the listings.
