davidcyclebackI notice the seller doesn't say it is vintage. The seller says the stock is
double-weight (which means the paper is thick), which wasn't avaiblable Pre-WWI.
The image itself, with the black border, is highly unusual for a period
postcard-- stands out as unusual. It has a stain on back, but a stain doesn't
mean anything age wise. My yesterday's receipt from lunch can have a stain on it.
Foxing (reddish/brownish age spots), on the other hand, is a strong sign of
age. Also, if the rppc is supposed to be from around 1901, the paper should be
bright white not toned. It was later paper (c. 1910s and later) that is toned.
Though, it's hard to judge tone from an eBay scan, due to variations is scans and
digital cameras.
If the paper is double weight (and the seller says it is, so there should be
little debate there) and fluoresces brightly under black light, there's little
question it's modern.
