I've written about Rhyne a few other times, including this feature highlighting him as minor leaguer on the O's 40 man roster back in February 2010, but didn't have a signed Orioles card of his until recently.
These offerings from Bowman and Topps are likely the only two O's cards he will be featured on since his time in the organization is likely over. I really waffled about which card to keep in my collection: the picture on the Topps card is far superior while the autograph on the Bowman cards stands out much better. I ended up going with the Topps card since the image is pretty unique and Hughes had more room to stretch out his signature.
Good luck with your future, wherever that may be, Rhyne!
