In a six month period many years ago, I won three Garfield lamp bases that were listed as Garfield desk lamps or as tv lamps. I won the one base for $4.99. That is why I have four Garfield lamps and only one has the proper cap. The fourth one was listed as a lava light and I found it by searching "garfield light".
Love the lamp
own 2 myself,
you have to be very general and specific at the same time in your searches by using proper keywords
