eBay's Purchase History only shows the current year, or either of the two most recently completed calendar years.
If you exchanged feedback, you may be able to find some information about your transaction by checking your feedback left or received.
You can request a report of your older transactions here:

Reports take a week to generate, and then you must use the resulting link within another week before it expires. Transaction data is quite basic: item name and number, date, price, shipping, seller username. No pictures or descriptions.
