Considering that you can expect to pay about $150 USD for this publication, I think that if your interest in astronomy is casual, you will be disappointed in the atlas. I think the atlas has great historical interest and value, so hard-core deep sky aficianados might appreciate it more. Below you’ll find images of the blue master chart, an image of a “typical” yellow plate (not absent of objects, not plastered with them either), and a close up of the plate, featuring the clusters NGC1869, NGC1871 and NGC1873. I observed this group on March 25 2009 from the 8000 foot level in the Atacama desert, Chile.
