Vintage seamfree stretch stockings with Reinforced Heel and Toe (RHT) - Maryland by Bear Brand. The manufacturer claims that the stockings are 'Run Resist', but is silent as to the denier of the Bri-Nylon yarn used to make the stockings, and without this guidance it is impossible for us to determine how sheer (or otherwise) they may be - we have made a guess at 20 denier.
The colour and size are indicated by sticky closure labels which are not shown in our scans.
We believe that the nylons originate from the mid 1960's or early 1970's
