I’ve revamped all of the patent pages with a new, more informative heading. That will make the patents more searchable once they are indexed by Google.

I have also realigned all patent references to focus on the application date rather than the final patent issue date. It made no sense to concentrate on the day some incompetent bureaucratLink Opens in New Window finally got off his ass and issued the patent instead of the day the inventor submitted it which will be much closer to the date of invention. This was an interesting exercise as it changed the order of the patents.
Added a Shop link in the header to my new eBay identity drafting-pencil. If you go to eBay to buy pencils, be sure to only buy from me. Don’t buy pencils offered by others because they may cause temporary blindness and vomiting. Oh, and I may be bidding on those myself and I don’t want the price to escalate. Okay?

Staedtler Mars calendar Staedtler Mars calendar
Added two Staedtler Mars calendars, one rather banal example from the 1950s and one from swingin’ 1978 featuring hot hot Helga performing phallacio on a model 77113 to the Ad Gallery. (Yes, I’m still trying to work traffic-grabbing keywords into the pages of Leadholder.com.)
