SQL Server 2012 :: Selecting Data From A Change Log Where Date Falls Between Two Rows

I need to extract a price from a package solution table that was current on a certain date.

Columns are:

Product_Reference int,
Change_Date int, -- Note that this is in yyyymmdd format
Price decimal

So for one items you would get

Product_ReferenceChange_DatePrice
100014200401281.59
100014200605131.75
100014200802121.99
100014200906252.35
100014201002242.50
100014201107151.10
100014201205151.15

The challenge is to return the price of the item on 20070906. In this example 1.75.

I've tried joining it to itself

SELECT DISTINCT p1.[Product_Reference]
,p1.[Change_Date]
,p1.[Price]
FROM PHistory p1
INNER JOIN PHistory p2
ON p1.Product_Reference = p2.Product_Reference
WHERE p1.Product_Reference = 100014
AND p1.Change_Date >= 20070906
and p2.Change_Date < 20070906

But it returns the price above and below that date.
