Hi Rick,
I have been collecting antique bulbs for most of my life, and I too have experienced some of what you describe. Fortunately my wife has always enjoyed the fact that I get much pleasure out of this interest and has always supported and even encouraged my collecting interests. I do recall a Christmas party a few years ago at which someone asked me about my bulb collecting and I was greeted with several amused smiles and barely disguised laughter from a few of the guests. However, I think with there being so much interest in antiques of all kinds that more people are at least respectful and sometimes even interested in the subject when it comes up. And why not? Where would we be without the invention of the incandescent lamp? And the old bulbs provide an endless and fascinating variety of shapes, filament design, bases, stem presses, and so on, not to mention that the elegant shapes of some of the early ones are irresistible - they are handmade works of art. My church recently had a live auction, and I decided to auction off a private showing of my collection. I am delighted to tell you that several people were bidding on this, and it ended up going for $400! So, keep collecting proudly! And anyway, if you enjoy it, who cares what someone else thinks?
