`Error in test card graphic ==  The 50 to 300 and 325 to 575 resolution test scales are not quite right.  Mainly it's the 325 to 575 scale.  Being a resolution scale, the lines should get progressively thinner toward the lower (larger number) end of the scale.  That doesn't happen at all between 325 and 575, and it happens a bit too much with the 50 to 300 scale (the lines are too thin at the 300 end).  I don't know the source of the graphic, but it would be nice if this error could be corrected as it appears to be perfect otherwise.     :You have a good eye. I see it too after comparing TESTPATTERN RCA 3.jpg graphic recreation to the previous image RCA Indian Head test pattern.JPG (when enlarged), and also when compared to the original artwork at the bottom of Chuck Pharis' web page.  :Click on any image to find its source.  linked the current version, TESTPATTERN RCA 3.jpg on 21:57, 17 January 2008, to replace RCA_Indian_Head_test_pattern.JPG . Info at TESTPATTERN RCA 3.jpg says uploader Emdub510 ``self-made (redrawn from source art in public domain)``.  :Another point is that the recreated Indian is too detailed compared to the original master copy, or original ``copy ready`` artwork above it. The Indian on the original master copy appears to have been ink-outlined to reduce detail. One can just barely see the ink outlines.    == `
