LIRR Postage Stamp themed items

I have a number of LIRR stamp related items at: http://www.trainsarefun.com/trainsandst ... stamps.htm" onclick="window.open(this.href);return false;
Anyone else with material of this nature?
Here's one: Postal rates: March 3, 1863 .06 first ounce (.03 for 1⁄2 oz) Roughly .30¢ in today's money to send. But, what buying power in the Civil War era!
I would date this cover as DEC 17, 1863-1882 as the rate changed to 4¢ October 1, 1883. Probably closer to 1863 as the cancellation is a very old type and reads: LONG ISLAND R. R.

Here's one a bit more recent: Oyster Bay Station placed on National Register of Historic Places, 7/06/2005

Perfect, come them coming.
