WWPCM - World Web Playing Card Museum - The International Web Museum of playing cards. Probably the most famous site among collectors of playing cards. I am constantly amazed at the hard work and patience of Alexander Sukhorukov - the author of this project - who for many years (the site started in the distant 2000th year) has been collecting scans of maps from around the world and uploading them daily to his site. Many collectors use it as a kind of catalog.
House of Cards. - The site of playing cards by collector and publisher of Anatoly Bovtruk's decks and created to assist in collecting.
The Queen of Spades. - The site belongs to the famous Kiev collector of playing cards Wheat Galina. The site contains maps of various directions from many countries of the world.
