Microprinting

• ... that microprint was invented by Albert Boni in 1943?

• ALT1:... that microprint can be found not only on currency but also bank cheques, postage stamps, security seals, and other important documents?
• ALT2:... that the first US postage stamp to incorporate microprinting was the American Wildflower Series in 1992?
• ALT3:... that true microprint (text less than 1px tall) can not be reproduced by digital methods but microtext can (text approx 4 to 1px tall)?
• Comment: I have spent the past few days significantly expanding and improving this article.

5x expanded by David Condrey (talk). Self-nominated at 09:09, 8 October 2015 (UTC).

• I will review this one.... Hassocks5489 (Floreat Hova!) 19:50, 12 October 2015 (UTC)

• There is some further work needed here. An expansion of about 2.5x has been achieved so far (based on expansion starting on nomination date of 4 Oct), and a large number of good sources have been introduced, but more content is needed to reach the DYK yardstick of a 5x expansion. There may be scope to include info about microprinting on other countries' banknotes, for example. There is an {{Expert-subject}} tag in one section, which I think is justified, but some expert help would really need to be forthcoming before this could run at DYK. Has the Science wikiproject been approached directly? Could the Numismatics and/or Technology wikiprojects help as well? There are also some paragraphs needing citations.

This article has excellent potential, especially given that good sources have been added as part of the expansion so far, and it would be good to keep this nomination on hold for a while to see if further expansion could be achieved. I have watchlisted the article. Hassocks5489 (Floreat Hova!) 20:41, 12 October 2015 (UTC)

I have noted this article is currently being peer-reviewed, so am prepared to continue to keep this nomination on hold for the time being. Hassocks5489 (Floreat Hova!) 12:22, 23 October 2015 (UTC)

• As noted above, the article has not been sufficiently expanded: it started with 2165 prose characters and is currently at 5553 prose characters; it needs to reach 10825 prose characters, or another 5272 prose characters (it has been expanded 3388 prose characters so far). However, nothing has been added to the article in the past four weeks, and the peer review was completed on October 5 and acknowledged on October 21. Absent a near-doubling in its current size in the very near future, the article will not be eligible; in that event, your only hope is to take it through the GA process. One thing the peer review does not point out is that the lead of the article is supposed to be a summary of the rest of the article and nothing significant should be listed there without being in the body of the article in greater detail: the third paragraph of the lead, about Boni, belongs in the body, with only a summary of that info in the lead. Best of luck! BlueMoonset (talk) 21:26, 9 November 2015 (UTC)

• No edits have been made to the article since BlueMoonset's comments. Nominator's userpage indicates he is on a wikibreak with no set return date. As nothing is being done to address the nomination's problems and there is no reason to expect this situation to change any time soon, it would appear to be time to close this nomination. --Allen3 ^talk 14:15, 18 November 2015 (UTC){{subst:DYK bottom|passed=no}}
