I have a bulb that can best be described as follows: When lit, it has a single red rose, partially opened bud, green leaves and a green stem. It is a smaller bulb similiar in sized to a 25 watt decorative bulb. I got this bulb in 1968 from my dad's mom, who got it from her mom. Is there a way I can find out who made the bulb, when it was made, how much it was worth, etc? I'm new to this, so any help would be great. Thanks ahead of time.
