Under magnification, the illustration in the Scott catalog of the stamp with the white background clearly has a 2004 date, making it 3756.
The illustration of 3756A with a white background on Bardo's site has a 2007 date. But below the single stamp illustration is a scan of a full pane on which the background is not white.
I have both of these stamps in my collection, including plate blocks and full panes. While the background on my 3756A stamps is a different shade than the 3756, neither is white. A scan of the plate blocks appears below. 3756 is on the left.
None of the stamps I have (there's also a coil, Scott 3612) have a background anywhere near as white as the illustrations in the Scott catalog and on Bardo's site. Does anyone have a stamp of either Scott number with such a white background?
