One of the most common requests from my customers is for cosmography and astronomy related prints and charts. They are actually quite rare. There are some nice reproductions on the market, but if you are like me and you like original old pieces, you have to look pretty hard to find them. I have some nice cosmos-related items in my shop at the moment to bring a little bit of the nocturnal outside in.
A few other fun items in store:
A space age lunar globe and some great vintage books on stars and constellations.
An interesting aside on this subject: The well known science professor and science fiction writer Isaac Asimov lived across the street from my shop while growing up. According to local legend, his father had a candy store in what is now my storefront. Kinda cool.
