WANTED: IGCO in a diamond

[jbecherer]

Looking to purchase items with the IGCO in a diamond mark or intertwined IGCO emblem. Type of bottle is not priority, time period is my key focus, 1900s, pre-ABM. Thankjpb

I have plenty of unembossed meds with that symbol but most of them are ABM. I will try and see if I have ones that are BIM.
