Joe K9LY in Chicago has several home-made adhesive labels for the battery tray of the Eddystone EC10 and EB series receivers. He will send 2 pieces in return for:

• those inside the U.S.: a self-addressed stamped envelope (at least 6 inches long) with first-class U.S. postage (55 cents / “Forever” stamp)
• those outside the U.S.: Email me and we will work something out. How about a picture postcard via post of the city or region where you live? :-) 

Email Joe for postal address.   K9LY [at] arrl [dot] net
