Krause\n{ .img-caption }\n\nObviously, I needed to photograph every one that I came across. I did a bit of reading on the topic and learned that they're called _Foundry Marks_ or _Sidewalk Stamps_, and that people who photograph them are called stamp collectors, so I accidentally got a new hobby. \n\nBefore we even moved here, I already had a favorite example of the genre: there's a stamp in the sidewalk outside the entry to the Whitney Museum in Manhattan notifying people that the museum is private property, and declaring that your access is by revocable license only. I suppose that stepping over it is like clicking the terms and conditions agreements on software that no one reads. \n\n<br />\nWhitney Museum of American Art\n{ .img-caption }\n\nThe older ones (none of these are dated -- curious the actual vintage, but notice that they're all on sidewalks old enough that the individual stones in the aggregate are showing) have these little plaques: \n\n<br />\nBy Klinck. Super-simple.\n{ .img-caption }\n\n<br />\nDrehmann, on Parrish St in \"Philada.\" That is going to become my standard abbreviation for this place now.\n{ .img-caption }\n\n<br />\nDrehmann again, this time on Glenwood Ave in Phila.\n{ .img-caption }\n\n<br />\nPennsylvania Asphalt Paving Co, also in Philada'\n{ .img-caption }\n\n<br />\nUnited States Artifical Stone Paving Co.\n{ .img-caption }\n\n<br />\nWalsh Cement Work\n{ .img-caption }\n\nThe more modern examples are just literally a stamp placed into the setting concrete. \n\n<br />\nBonilla\n{ .img-caption }\n\n<br />\nFosonini\n{ .img-caption }\n\n<br />\nThe King of Concrete!\n{ .img-caption }\n\n<br />\nI like the upside-down '2' characters\n{ .img-caption }\n\n<br />\nSpade\n{ .img-caption }\n\n<br />\nVentura\n{ .img-caption }\n\n<br />\nThe reversed ꓘ in \"MARꓘ\" is nice.\n{ .img-caption }\n\n<br />\nThis brutalist METROPOLITAN is very striking.\n{ .img-caption }\n\nUpdate 08 August 2025\n\n<br />\nVOGT Construction, seen on my walk to the dentist this morning\n{ .img-caption }\n\nOther Entries {#other-entries}\n\nNot from the installers, but in the sidewalk anyways: \n\n<br />\nIn front of one of the houses on Boathouse Row\n{ .img-caption }\n\n<br />\nA mosaic goat\n{ .img-caption }\n\n<br />\nToo late to try any of Ashley's Water Ice\n{ .img-caption }\n\n<small>View Change History</small>",
