Isn't this a lovely wheel? It's a star finder produced for the Junior Astronomy Club at New York's Hayden Planetarium. The copyright date is 1952. The wheel is 8.75 inches square and is in very good condition. It's one of my favorites.
It's all here: Aries, Cygnus, Draco, Vulpecula! I like how the instructions tell you the stars are shown as they appear at 9 pm on any date. Kids need to be in bed and not up later than 9 o'clock! The back has a chart showing the position of the bright planets for 1954 and most of 1955. I wonder how often they updated this wheel? All in all, a very handsome and useful wheel for the budding astronomer! Here's a handy wheel for all you gun nuts. It's from the early 90s and is pretty self-explanatory. I wonder how these were distributed? Gun shows, perhaps? It is eight inches in diameter and in like-new condition. I think it's rather unremarkable in its general design. The least they could have done was include a little drawing of each pistol in a window.
Here's a wheel from my own back yard. It was distributed by the Edwards Aquifer Authority a few years ago. From top to bottom, this measures 8.75 inches. The disk is 6.75 inches.
It's kind of a fun way to communicate how to conserve water. I did not know you shouldn't use the toilet as a trash can! I wonder if Heloise knows that? I'd better tell her! According to Wikipedia: The Edwards Aquifer is one of the most prolific artesian aquifers in the world. Located on the eastern edge of the Edwards Plateau in the U.S. state of Texas, it is the source of drinking water for two million people, and is the primary water supply for agriculture and industry in the aquifer’s region. In addition, the Edwards Aquifer feeds the Comal and San Marcos springs, provides springflow for recreational and downstream uses in the Nueces, San Antonio, Guadalupe, and San Marcos river basins, and is home to several unique and endangered species. |
