Here are a few old lightbulb ads that I've scanned. Many people sell these genuine vintage ads on eBay (and yes, I bought mine there too), but the asking prices are usually crazy... (for example, $10 for just one ad!) Fortunately, I found a whole bunch for about the same price. I believe they need to be shared with anyone who may be interested, so I've put them here for you. These would look great framed, placed close to your lightbulb collection display, if you have one. These ads came from a 1918 issue of National Geographic magazine. These are large images, so please don't forget to check "fit to page" on your printer software program before printing them.
