APC / SSK / CVP / ATM - USA #CVP91 strip of 3 with 1 missing FOREVER

Description

USA #CVP91 with missing word FOREVER on a strip of 3
Most errors from the APC / SSK machines are "man-made" (such as inverted printing or overprints); this however, is a "machine-made" error!
This strip of 3 "FOREVER" flag stamps has the word "FOREVER" missing in the middle stamp - the only thing shown is a thin line.
So what happened?  Apparently some sort of "slippage" while printing caused this anomaly.   The top and bottom stamp printed properly.  On the middle stamp, the whole indicia (ie: barcode, serial # and "line") are a bit further down than on the top & bottom stamps.
Please note that these stamps were printed from the "old" machines in 2016 (specifically, February 5, 2016), which is easily seen by the fact that the serial number (reading sideways) begins with a letter.   On the new machines that were installed in August-October 2018, all serial numbers now begin with a number.
If you collect APC / ATM stamps, then this will make a nice addition to your collection!
Will only mail via tracked 1st class mail within the USA; foreign shipments only via eBay's Global Shipping Center.
Note: I have 2 of these strips of 3, each identical; the scan shown is representative of what you will receive.
