Disabled American Veterans (DAV) 32¢ Franking

Following are examples of DAV covers franked with thirty-two cents postage.  The 32¢ rate period began on January 1, 1995 and ended January 9, 1999. 

From its continuing use of four 5¢ plus four 3¢ stamps, we can assume DAV had found this the most effective franking during the 32¢ rate period.

All stamps on these covers are untagged and all have four gravure printed 5¢ Circus Wagon stamps (Krause-Minkus 1077, Scott 2452D) and four intaglio printed 3¢ Conestoga Wagons (Scott 2252a, Krause-Minkus 883zx). The Conestoga Wagons are all on the newer whiter paper.

These examples are from what could be called the late period of the 32¢ rate usage.  Design and placement changes have been made to conform to new postal regulations.  All have bar codes preprinted over white paper rather than the simulated texture of the rest of the envelope.  All also have Facing Identification Marks (FIMs) preprinted on the upper right of the envelopes.  To receive the Automation Discounts offered for Standard Mail (formerly called Third Class) all outgoing and enclosed return envelopes now must have these FIMs and preprinted bar codes.  For more information on FIMs click here.

These covers no longer have the traditional blue or red diamond design on all edges.  The removal of some of these these edge designs is necessary for postal equipment to accurately find and read the FIMs and bar codes. 

Precisely dating these covers is difficult as the covers are "mint" examples and do not have any cancellations.  Some covers do have the date received noted by the recipient.  From the information available and the markings and return labels, I believe these covers are presented chronologically.  I would very much appreciate any information/insights which could help more accurately date these covers. 

 
 
This first cover shows the bar codes printed on white paper and also has the preprinted FIM.  However, the 3¢ stamps are placed partially covering the FIM making it difficult, if not impossible, for USPS equipment to find the marking.
The far left Circus Wagon has a plate number S1.

 
The second example removes more of the decorative blue edge markings and lowers the placement of the 3¢ stamps so they do not cover the FIM printed on the upper right of the envelope.  At the left is a red, white and blue flag sticker with the word YES!
The third Circus Wagon stamp from the left has a plate number S2. 

 
 
The edge design on cover three is similar to the previous cover but has the Circus Wagon stamps applied on the right and lacks the circular flag sticker.
The second from the left Conestoga Wagon has a plate number 6.  This cover was mailed in July 1998.

 
 
This cover lacks all edge markings.
The Circus Wagon on the far left has a plate number S2.

 
 
The fifth has new bolder red, white and blue edge markings simulating a United States flag. Note that the edge design does not cover the FIM or the lower portion of the envelope containing the bar code. 
The third from the left Circus Wagon has a plate number S1.  A similar cover is known having a plate number S2 on the Circus Wagon.

 
 
While each of these covers now has 1) preprinted bar codes on white backgrounds 2) FIMs and 3) edge markings designed to allow postal equipment to find/read the preprinted markings,  it is interesting to note that none of these covers has a stamp which is tagged and therefore cannot activate the USPS canceling machines.
