Here is probably the smallest bottle I have. It's probably from the 1920s-1940s (found in a dump of that age) but has no markings. ABM, possibly a perfume bottle. Anyone seen this before?
Very cool smalls!
DavidW - Haven't seen that exact one but have dug a few ridged perfumes. 20s–40s is about right for the artifacts I've found with them (such as "Federal Law" whiskeys and embossed ABM milks).
