This is a beautiful iridescent ice blue lidded canister.  It has a diamond pattern and even though unmarked, it's likely Imperial Glass.   It measures approximately 9" in height,  5.25" in width, and 4.5" across the mouth of the canister.   It is in good vintage condition.   I can see no chips or repairs.  However,  there is a tiny crack on the lid (it is superficial).   There is a "haze " in a few places on the top of the lid (see pictures).  There is also a "hazy" spot on the side of the canister (see pictures).  There is a rough spot on the underside of the lid (see pictures).  I believe this to be a production flaw.
