Sales Comparison by Items Report

Question

Hello Experts,
Is there a report in B1 that compares total sales by item between two periods? If not, could anyone help me with a query?
For Example:  Total sales for item A0001 between Jan-Oct 2010 is $10000 and Total sales for item A0001 between Jan-Oct 2009 is $5000
When i enter a date range i should get result like this:
ItemCode ItemDesc Jan-Oct 2010  Jan-Oct 2009
A0001     Printer      $10000             $5000
