The International Herald Tribune newspaper ran an article on map collecting in its "Your Money" section, with advice for collectors from various experts, including George Glazer. Below is an excerpt; the entire article may be read on the International Herald Tribune web site.
"It's a huge field of study. It's like looking at birds," said George Glazer, who owns his own map gallery in New York that features maps ranging in price from $5 to $20,000. Glazer, echoing the advice of others, suggested that aspiring collectors focus on finding maps from specific regions and time periods, understanding that there is a pecking order to how antique maps are valued.
