Locate a Wurlitzer instrument or vending machine and look for the silver plating on the front. The logo will typically be printed on a silver medallion, although sometimes it is printed without the medallion.
Find the logo text, which will have the word "Wurlitzer" printed in a raised silver design. The logo itself does not have a picture, just the text of the company name.
Look for the logo on other Wurlitzer instruments. The company also manufactures instruments under the Gibson and Baldwin logo. All of these instruments use a simple printed design of the text.
Confirm that you have identified the logo by checking that the Wurlitzer name is spelled in all capital letters, the W and T are bigger than the other letters, and the T stretches over the I and part of the Z.
