I have picked up a copy of the Golden Age ABC, a booklet made in 1919 for the instruction of Children. It is in full colour, A is for Adam, B is for .. etc. It is in good condition, with some pictures drawn by a child about 85 years ago. My questions is - Does anyone have an idea of the value of such a booklet? Is it rare today? Before I look to sell it on ebay or the like I would love to get an idea of the value. Any ideas? Thanks in advance.
